General Mach Discussion / Re: HotKeys for Outputs

« on: March 28, 2009, 02:53:40 AM »

I think you need to use a script such as  ActivateSignal(OUTPUT1)  assign this to a button and then hotkey to the button but I am quite new to this so there may be a better way of doing it that I don't know of yet.

Hi Rick

A similar problem was posted recently and the outcome was that the motor connections were incorrect.

Following up on TP's posting you could also check for backlash in the leadscrew, leadscrew moving in the thrust bearing, leadscrew nutplate loose in it's mounting or anything else that has worked loose on the axis drive chain.

Just another thought - when you are converting your DXF files and using tool offset, if the AutoCad lines are not all joined and a small gap is encountered the offset can revert to the other side of the line. (I know what I mean here but I am not sure I have explained this very well). I think it is called joining polylines.

Hi Roberto,

As Brett has already said it sounds like missing steps to me. Remember that lost steps in one direction will become gained steps in the opposite direction. I suggest that you check for any binding on the axis travel as well as the leadscrews.

Hi Larry,

I know this is an old post but as Bob said "for those who follow"

Hello Everyone,

I found a post in the Mach1Mach2CNC group on Yahoo with the solution.

For those who follow...

You must select one of the direction buttons before clicking the Write button!

Another update. Just thought you may be interested in this.

I have added two buttons to the Mach screen one titled 'Laser ON/OFF' and used Scott's VB script to perform this function. The other button is titled 'Home to Laser' and uses the following script.

Xs=GetOemDRO(59) 'Xscale DRO
Ys=GetOemDRO(60) 'Yscale DRO

Xmove = -72.8719 * 1/Xs 'move distance adjusted for X scale factor
Ymove = 10.7156 * 1/Ys 'move distance adjusted for Y scale factor

DeActivateSignal(OUTPUT5) 'turn off laser

Code "G91 G0 X" &Xmove & "Y" &Ymove ' makes an incremental move the distances that you set
While IsMoving () ' waits while that happens
Wend

Code "G90" 'goes back to absolute moves

DoOEMButton (1008) 'zero X DRO
DoOEMButton (1009) 'zero Y DRO

As I use the DRO Scale settings to scale my engraving work to fit the size of the blank I have included a calculation to position the cutter relative to the laser irrespective of the scale settings.
