Hey all,
I just received my first CNC machine, a JCUT 6090, with a JNC-40M (USB) board. The instructions that come with it are less than clear ;)
If any of you are running this same (or similar) setup, would you be willing to help a fellow out with some configuration (like pins and Ports)?
Thanks!

Hi DC Ross,
I also have a JCut 6090B router with JNC-40M. I ordered my machine to run with Mach3. The machine is functioning OK, but you need to create your own machine as ArtSoft suggests. Mine came with an already configured Mill, however the screen is in Chinese. What I've done is, I screen captured every config screen the way they did the configurations, than I created my own Mill, and just set everything up as they did it. You'll have to fine tune the motors (Config-Motor tuning), it was a bit scary when used for the first time the "Home all axes", but that worked too. You'll have to set up the "Soft Limits" also. I only have one problem now, how to wire in the water pump to start when the spindle starts.
Good luck, Mike

Thanks for the reply, Mike.
If you want the English screen back, you can go to View > Load Screens, browse to the Mach3 folder, and select 1024.set.
Instead of re-creating the mill configuration, you could also have made a copy of Mach3Mill.xml, this is the Mill config file.
What numbers did you end up with for the Motor Tuning and Setup?
Thanks!

Hi to All
I got a JCUT 5060 and was able to setup the machine properly. Except when you jog X and Y axis using the keyboard shortcut keys the motor stalls. I have check the mechanics and seems to be OK. Did you have the same problem?
-
Hi DC,
I just tuned the motors by ear to eliminate the jerking at the beginning & end of the moves (acceleration & deceleration). I won't know if they are OK until I calibrate the axes, e.g. to make the axes to move the correct distances.
Have a nice Day.

Thanks again, Mike. One more question: I haven't yet been able to get my spindle spinning. All my settings relating to the spindle are correct according to the JNC manual, would you be able to provide your settings?
renatom: I haven't had that issue, but I completely cleaned the machine, including wiping the ball screws and rails down with acetone, blowing everything out with compressed air, then lubricating all the moving bits. When they were built, they weren't cleaned at all. The fabricators just left all the shavings and crap from drilling and tapping and whatnot in the machine.

Hi DC,
I didn't change any of the spindle settings they made. I MDI-d a spindle command: S13000M3 and hit enter. The spindle started up, very quietly
I may add, after about 1/2 minute I stopped it by M5 command. Didn't want to run it without the pump for long.
If this window would allow me to attach a picture I would post the screenshut of my settings. If you email me, than I will send you my settings.
Mike

Ah, I configured the spindle settings to what was shown in a screenshot in the JNC manual, which was different than what was pre-configured. I reset the settings, and now the spindle works. I probably should have thought of that first :)
Have you been able to automatically start the cooling pump?
-
No, I hadn't as yet. Today I'm rewiring my X so it doesn't drive the the rotary any more. They fooled me into believing, that it was a 4 axes machine when it is only a 3 axes one. Purchased an identical axis driver, and that'll now drive the rotary axis. As for the pump, I haven't given it much thought, I suppose I can just plug it into the rear of the step up transformer(220volt), until I figure out where to wire it into.
DC, I assume you know that many Chines companies make the Jcut routers, I was talking to three, before I ordered from "Jinan Jcut CNC Equipment Co., LTD" My contact was Shanny Chu.

Hi there, I'm the new kid on the block. I bought a Jcut 4040B a year ago and I've been using it with the crappy software that came with it with good results I guess.
So far I've been able to mill but I haven't been able to put the lathe or 4th-axis to work for several reasons, including damaged parts that were never replaced by the manufacturer and total absence of instructions on how and where to connect the part. In the end my router is half operational and support from the manufacturer has long disappeared on the issue.
For the few months I've owned the router thou I've been able to work with it but I'm trying to improve performance and get the lathe to work so I'll migrate the machine to MACH3 since my biggest problem is software right now.
Ideas anybody, maybe a sketch or a document from the manufacturer on how to connect the lathe on a similar machine?
Thanks for the support

Hi 888,
Like you, I'm also trying to get the rotary ( if that's what you call a lathe) to work. My machine was built as a 3 axis + rotary, what that means is that one of the axis, X or Y is swapped for the rotary when it is needed. As for me, this was not acceptable, so I ordered another axis driver, and wired it into the PLCX 6045M board. that board had provisions for 4 axis, however the rotary didn't work. The manufacturer told me I need an other 4axis board, so I ordered one, and now the rotary works. I still have to get a proximity switch for homing it, than to configure it to run with Mach3. It may be another to weeks before I can report on it.

Hi mvoros, thanks for answering. Yes, what I call lathe is the rotary axis. When I bought my machine it arrived bended so I just concentrated on learning how to use the milling bench and that's what I've done so far. Anyway, I don't quite get you when you say X or Y is swapped to the rotary when needed, is that done automatically?
The other problem with my rotary is that it wasn't connected when the machine arrived (quite conveniently for the manufacturer) so I haven't even figure out how to do it, but you say that replacing the controller board could help. Where can I buy one? At some point I'll have to do it anyway if I want my router 100% operational.
Thanks for the tips and good luck with your proximity switch

Hi Friend,
You leave lot of unanswered questions. How did they sell you the router, 3 axis + rotary? ( typically this is how they build the routers in China) If so, than you have X, Y, Z axis plus the rotary. This makes your machine just 3 axis and a rotary (or as they call it: lathe). Is there a connector at the end of the rotary wires? If there is, than there must be a connector on the control cabinet to plug it into. In this situation, you should have about a foot of wire sticking out of the cabinet that can be unplugged. Than you have to plug in the the rotary's plug. For the rotary motor to run, it needs a driver, therefore, it takes the X axis or the Y axis's driver to to run the rotary, depending witch axis does the rotary revolves around. Mine rotates around the (long) Y axis. If you bought the rotary separate, than it's a different ballgame. I need to know what exactly you have, before going into how I've done mine. Post pictures, or email me the pictures, of the rotary, the inside of the control cabinet.
Have a nice day,
Mike

Hi Mike, long story short the machine shipped without the rotary, when I requested the missing piece it was expedited but it came unusable and the manufacturer (Chinese indeed) didn't use insurance for the parcel so I ended up with a half operational router and no support from the seller. At least I could learn milling at that point and sad but true so I consider myself very lucky of what could have been a more catastrophic transaction.
The only thing I see is the cables from the stepper motor for the rotary that need to be connected to the controller board. I'm fairly new opening the electronics cabinet on my router but I'm starting to loose my fears on the issue. I don't see a plug so that means I'll have to connect the motor using the other motor's color codes as reference. I'll just have to figure out the correct terminal block on the board (if there's one otherwise I'll have to get a new board).
I'm pretty sure the rotary will be revolving around the Y axis just by looking at the setup of the router. The other thing I'm lacking is a module to control the rotary from my current software which is the main reason I'm on this forum.
Since I'll have to get the software installed in order to control the hardware I guess my first approach will be taking a good look at the board. I'll try to post some good pictures of it.
Thanks.

Hi,
Well it seems I won't be much help to you. Try and find someone near you that went thru such installations before. Since the rotary was sent to you at a later date, the motor wire colours may not be the same as the other motor wires. I think they just went to a warehouse picked one up to send it to you. Sounds like your router was built to be just a 3 axis machine. If you want it to be 4 axis (meaning the rotary), than you need another driver, like you now have for the X&Y, and probably a 4 axis USB control board also. Is the software that runs the machine now NCStudio?
Mike
-
Yeah, somehow it's a possibility, that would explain why I never got support back from the manufacturer. If that's the case I will have to buy the new board to include the rotary, I've been looking on Ebay and there's a couple options that I'm evaluating right now.
The software I'm using right now is NCStudio indeed, not very useful for my purposes but it taught me how to run basic operations. I mean the router could have been a great one if the manufacturer would've included a manual or some links to videos on their product, but I guess that's too much asking, or they're just interested in selling and after that they just don't care what happens to their products.
Well thanks Mike, I really feel more confident to start the brain surgery on my router. It'll take a while I guess.
-
I had mine built, so Mach3 will run the machine since I'm used to it. Did yours came with a CD? If it did there should be a manual on it, although it is written in Chinglish.
very hard to understand, but it could be some help to you.
Good luck,
Mike
-
Man you were damn right, I got ripped by this company. I opened the router and there's only three motor controllers clearly labeled as X,Y and Z. I already ordered the extra controller and a new break out board. I'll try to reuse the rest of the stuff but I think I will be dealing with the rewiring in a couple weeks.
Thanks for the advice.

Is there anyone in Los Angeles area that could help me with a JNC 40M setup?
-
Ah, I configured the spindle settings to what was shown in a screenshot in the JNC manual, which was different than what was pre-configured. I reset the settings, and now the spindle works. I probably should have thought of that first :)
Have you been able to automatically start the cooling pump?
can you post a picture of this manual? I haven't got it... mine is a JCUT1218B. nice machine. I need to swap x and y and I do not know how to setup the spindle in mach motor tunning... I noticed that the bed is not levelled...I guess I will have to mill a wood template to get all flat.
-
by the way. machine is moving fine and x,y,z movement is accurate. however I have an issue with the feedrate. I am not able to get it right... when moving at 5000mm/min, with override 100% it shows 1500 value.
If input a G code with f value, it still runs full speed...
any clue how to fix this?
-
look at feedrates... any clue?
-
that image seems to show g0 active
what does it do if you type G1 x50 then G1 x200?

thanks for the reply. I finally managed to setup all the machine... ;)

hi, i'm new in cnc and starting to learn from now on..... i just bought a jnc-40m engrave cnc board one week ago. however i failed to install the jamen usb driver into my new computer asus used windows 8. the device mgner shown the yellow color. i search around the web, couldn't get any inform. for windows 8. May i know anyone have this latest jnc-40m driver? i couldn't find their official web to download the driver too. if anyone can help me in this issue really appreciated. please e-mail me the driver to alexcfw73@yahoo.co.jp thanks.

hi
it work fine with windows 7

where have you buy this carD and how much please ?
-
Hi, thanks for ur inform. i bought it from china online IT tech.
-
HI fabrun, the link i download the software before, i installed successfully. However device manger still shown the yellow color. When update hardware driver again,
windows shown an error that software corrupted.....
-
can you give me a link and price please ?
-
the problem is certainly with windows 8
you must swap to windows7
-
hi fabrun i bought it around us 250 in aliexpress, need to check back the history link...thanks
-
Well, I tried to add a touch off plate (for auto-zeroing the Z axis) following the instructions, and I think I fried my board. Translating Chinglish is a skill that I apparently lack.
Like alexcfw, I found a replacement on Aliexpress for about $215 USD, but haven't ever bought anything on there before. Here goes nothing :)
-
the pic page 28 is clear and simple
one plate, one led, one resistor!
i made it and it works perfectly
-
Yup, that's exactly what I did. It worked once, then nothing...
-
I had one of these in my JCUT CNC machine. Drivers failed to load (yellow) I tried on multiple machines and found one that would work. Even with the driver loaded it would not interface with the cnc. This could have been in part due to the non-existant setup instructions for pin config or any other interface instructions. I finally gave up, Installed a Smooth stepper interface and new break out board and everything works great!. I would ditch the JNC-40m and buy the smooth stepper for about the same price and with it you get GREAT support!
my two bits.....months in the learning.
-
fabrun: it turned out to be a case of extremely bad timing. The board was fine, but a connection in the power plug was intermittent.
I am having a problem with the Auto Tool Zero button, if you wouldn't mind taking a look, the post is here: http://www.machsupport.com/forum/index.php?topic=25116
Keleide: sounds like a good upgrade!
Thanks :)
