General Mach Discussion / question about THC and the bob i am using??

« on: January 01, 2017, 11:10:22 AM »

Hi, my name is Chris been reading a bit here but time to ask the experts here......I have two friends who built a cnc plasma table 5x10 I believe, the friend who did all the computer end and wiring of this table passed away in April in a Automobile accident the other friend did all the machine and welding of this table. I have been trying to help him out ever since to learn how to work this table, unbelievable what you can learn when you are forced to. We have finally been able to cut some names and other small stuff but when we tried adding a Proma 150 THC well we can't seem to get it to work. All these parst were ordered from cncrouter parts.com to run the system there using Mach 3 that is on a laptop that is going to a Ethernet smooth stepper, then to a 5 Axis CNC Breakout Board Interface For Stepper Motor Driver ST-V2 Link to the board and what it looks like http://www.omc-stepperonline.com/5-axis-cnc-breakout-board-interface-for-stepper-motor-driver-stv2-p-197.html motor drivers I'm not really sure of the part numbers I do know there is a total of 4 motors 4 drivers. I spent 6 hours yesterday till 11pm trying to figure out what we have done wrong to hook up the proma thc 150. I had it cut a straight line and picked the plate up on a angle to see if the thc would work, it will read voltage on the device but torch head doesn't not move up or down as it cuts.
I guess what my concern is now will this BOB work with this Proma 150 THC ??

http://www.omc-stepperonline.com/download/pdf/5_Axis_CNC_Breakout_Board_Interface_Users_Manual.pdf Link to the manual of this BOB.

I have arc, up, and down on the x,y,and z limit pins but again no clue if this is really right.

I've come to this forum because well I'm a bit desperate now. I feel we have almost exhausted every thing we can think of to make this thing work. We will probably go into the esab plasma cutter today to look over some stuff to see if that is all right on that end. i can get a good picture of how all this is wired but don't know how to post the picture from my phone unless I use Facebook link maybe. My friend who is older he has a good friend who is 89 and the guy is still a genius when it comes to electrical stuff like this, he was there during the time of our other young friend that wired this stuff up so he's been a huge help with helping us two idiots learn this lol

Thanks

General Mach Discussion / Mach3 or it could be sheetcam tng

« on: July 31, 2016, 08:34:21 PM »

I'm using mach3, sheetcam tng and autocad. My problem is this when i go to load the G-code into mach3 i can draw my part out with a sharpie on a piece of aluminum but my problem is the sharpie should pickup off the piece of plate move over drop down and draw out/cut and when the part is finished it should lift up above the plate. What it does is once i zero out Z and start it it doesn't lift up off the plat it draws a extra line. I think this has to be correct in sheetcam tng but not sure. Please bare with me treat me like computers for dummies lol
I dont quite understand the plunge rate if that is it. Any ideas? I have a picture what it did not sure if i can upload it here.

Thanks

General Mach Discussion / Trouble installing Mach3 License on windows 10 laptop?

« on: July 25, 2016, 01:27:48 PM »

Hi,

My name is Chris i'm from Covington, Louisiana i just got a used laptop from a friends roomate who wiped it clean and added
Windows 10, I told him i wanted a computer that i could run Mach3 sheetcamTng, and autocad. Laptop is a Lenovo T420S 8 ram and a 128 SSD card i think he said.
I cant get the mach3 to load as a license it keeps saying demo. I'm not good with computers so please bare with me i'm learning.
Friend of mine passed away in April and he and another friend built a cnc plasma from scratch and well the older friend is a machinist and fabricator he doesnt know computers so i am doing my best to learn and then teach him.
This thing is a full turn key operation, i wanted this laptop so i could learn autocadLT then sheetcam then mach3, when i know
It works from home then i can load it into the machine. I know there are many other programs out there Nd well my friend must have used these because they work. I just need to get this Mach3 license goibg and then l'm set. Any advice would be greatly appreciated i'm at a loss right now. I emailed airsoft about it and still waiting for a reply and just found the forum here.

Thanks
Chris
