General Mach Discussion / Elapsed time stops counting

« on: January 17, 2020, 12:53:42 PM »

Hello.
I don´t remember when it started, but the timer stops counting while cutting, not affecting anything else, but it would be nice to see the time.
I have been cutting the same toolpath 8 times today and the counter stoped after 03:42, another time after 03:45 minuttes.  About the same time every time with that code, but I can't se any suspicious commands in the code. 
I have been cuting 3 square holes, one gcode, and the timer stopped between cutting the 2. and the 3. square. Why not between the 1. and the 2. square?  It's doing the same thing.
Sometimes it stops cuting other gcodes after 45 minuttes, different time every time. 
Is there any theatment for that?

General Mach Discussion / Touch off plate script, something is wrong

« on: November 25, 2019, 11:46:51 AM »

Hello
I have been using this script for 8 years ( thanks Greolt :-) ), but had to reinstall everything on a new HDD and now the scipt is not working as it should.
Instead of zeroing Z on top of my table, it's zeroing on top of my PCB.
My PCB is 1.6mm thick.
Is there something wrong with the script?

PlateThickness = GetUserDRO(1151) 'Z-plate thickness DRO

If GetOemLed (825)=0 Then 'Check to see if the probe is already grounded or faulty
DoOEMButton (1010) 'zero the Z axis so the probe move will start from here
Code "G4 P5" ' this delay gives me time to get from computer to hold probe in place
Code "G31Z-40 F60" 'probing move, can set the feed rate here as well as how far to move
While IsMoving() 'wait while it happens
Wend
ZProbePos = GetVar(2002) 'get the axact point the probe was hit
Code "G0 Z" &ZProbePos 'go back to that point, always a very small amount of overrun
While IsMoving ()
Wend
Call SetDro (1.6, PlateThickness) 'set the Z axis DRO to whatever is set as plate thickness
Code "G4 P0.25" 'Pause for Dro to update.
Code "G0 Z10" 'put the Z retract height you want here
Code "(Z axis is now zeroed)" 'puts this message in the status bar
Else
Code "(Z-Plate is grounded, check connection and try again)" 'this goes in the status bar if aplicable
Exit Sub
End If

General Mach Discussion / Where is Auto tool zero script saved?

« on: November 09, 2019, 01:33:26 PM »

Hello.
My Windows XP stopped working after power failure, so I connected the HDD as a slave to another computer.
I want to back up some things.
I have copied the xml file, but cannot find the auto tool zero macro. 
It's just a text file inserted in VB Script Editor, but I can't start Mach3 without Windows, to see the script. 
Do you know if I can find it somewhere in Mach3 folder?

General Mach Discussion / Toolpath display

« on: August 13, 2014, 10:51:00 AM »

I have 4 axis foam cutter, but it´s not showing my gcode path on the display correct.
The left tower of the cutter is A and Z axis.
The right tower is X and Y axis.
Horizontal axis are A and X, vertical Z and Y.

Is it possible just to see one towers Gcode path on the display?
Because I have made some changes to the Gcode and I would like to see if it looks right before cutting.

Thanks

General Mach Discussion / LPT Led´s

« on: June 27, 2014, 06:14:49 PM »

Hello

I have my old cnc computer (which works great, but recently is freezing a lot)  so I just got a little younger Dell Optiplex 780 and have some problems with it.

The touch off plate which is connected to pin 15 is not working.  Probe Led is On all the time and when I change active high/low its off all the time.

There are the same settings on both computers, but the 2 rows of led´s, showing LPT pins in Diagnostics are showing different connections. Not the same led´s are On, on the 2 computers.

Someone told me it could be a driver, but what can I do about it?
Maybe thats the reason my touch off plate is not working.

X,Y,Z axis are running fine.

General Mach Discussion / A axis as extruder

« on: August 03, 2013, 04:08:00 PM »

Hello

I started my journey with reprap and Mach3 and I have 2 big problems.
This is one of them.

I use A axis as an extruder, which is pushing the filament down through a nozzle, but when it´s not printing it is supposed to retract / pull back the filament very fast, so it doesn´t drip and leaves strings through the printed part. Unfortunately it does.
I noticed that it´s retracting as long as the X and Y axis is traveling from one point to another. It should retract very fast before X and Y moves. 
You can see it on the video. Some fast retractions and a slow one at the end, time 0:24
http://www.youtube.com/watch?v=Hy1L3p4mNO8&feature=youtu.be

Is there some settings that can change this behavior?
I´m getting arachnophobic when I look at some of my parts :-)

General Mach Discussion / Forgetting last tool position after restart

« on: August 02, 2012, 03:38:40 PM »

I got another PC for my cnc and Mach3 doesn't remember the last tool position when I start the software the next day. My old PC didn't do that.
Sometimes I'm forgetting to Zero the axis and when something goes wrong, like loosing steps, I loose my zero.
I can`t find anything about it in settings.

And is it normal that I can`t jog with 3 axis at the same time? Sometimes I can, but usually just 2. I did try with 2 different PCs.

General Mach Discussion / Macros and dro numbers

« on: July 23, 2012, 11:35:35 AM »

Hello

I downloaded Z touch off plate macro and center finder macro and located them the right places with edit button script.
I was trying to type my plate thickness in the Offsets screen, but nothing is happening - plate thickness not set.
How can I see what number the dro`s are? I mean "GeetUserDRO (1151)" - how can I see which one it is on my screen? Maybe I'm trying to change plate thickness the wrong place.

And the center finder macro is moving very slow. It says FeedCurrent = GetOemDRO(818)  
Again here, I don't know where 818 DRO is and how to change the value.
I can see there is a little Feedrate window on MDI screen, FRO and F are set to 4 and that's the feed when centerfinder is active, but when I change the values to 10 and start Centerfinder, they are changing back to 4.

I don't know how to figure that out.

General Mach Discussion / Steppers not running smooth

« on: August 11, 2011, 07:18:52 AM »

Hello.

Im trying to change my way of milling and want to cut faster and not so deep.
But my motors are behaving strange when I try this. Specialy round objects and fillets.
Is it wrong settings, software, hardware, postprocessor or maybe just the limit of my steppers?

On the video Im changing the feedrate. Router starts to shake when it happens.

On the square cutting video, there are 4 bridges holding the part, so its cheating a little.

General Mach Discussion / Z axis can`t Autozero the DRO

« on: June 17, 2011, 03:37:28 PM »

It started today. After touching my touchoff plate, Z axis DRO always shows +269 in stead of 0. I mean in stead of 6.5 I set it to move up 6.5 after touching the plate. Auto zero is checked in config/home and limits.
I was playing with the button "set variable position" and "go to variable position" yesterday to see how it works.
Maybe this is the reason, but how can I fix that?
