Thanks, it works.

Thanks, I will give it a try.  What does 1.234 represent?

I found a conflict when the value goes negative and and scratched this out.

Distance = (GetDRO(30) * -1) + (GetOEMDRO(800) - GetOEMDRO(803))

Code "F30 g90 G0 X" & distance & "A" & distance

General Mach Discussion / Move to machine Zero
« on: November 10, 2014, 03:55:09 PM »
I am using screen commands and not file posted G-Code strings. While working with offsets, I would like to send the machine to machine Zero.  I set G28 and it works well except I am not able to control the speed.  Is there a code that will send the machine to Zero and set the speed too?  Also, I am have similar problems wit the Jog++ and Jog -- using OEM 314.  Is there a way to set the jog or any equal command to move at a specified and locked speed that is not a percentage variable?

Hmm,  I got it to work as below by changing to OEM codes, however, I have not been successful when using the standard code label.

Distance = GetOEMDRO(801)

Code "g90 G0 X" & distance & "A" & distance

General Mach Discussion / DRO Script help.
« on: November 08, 2014, 11:10:15 PM »
I am using the below script to move a gantry move or specifically a selectable rip fence for a gang-rip saw.  I need help redefining the DRO in the script from User DRO to X DRO.

Distance = GetUserDRO(1008)

Code "g90 G0 X" & distance & "A" & distance

The User DRO is the value of the coordinate used to position the fence.  I would like to capture the value from from the Y axis DRO in place of the user DRO.. The User DRO is a manual entry.  The Y axis DRO would be derived from the jog movement of Y which drives a laser line.

Thus the distance + X DRO rather than the user DRO.

Thank you, I was hoping for the Silver Bullet.  With any luck the screws will be the same and a pulley change will fix it.  But, your script works, I just need to make certain the operator can't get them out of sync.  The only real hurtle so far is in the jog mode.  I can jog X-A, but I have not discovered how to jog X-A in incremental mode.

I simulated the setup for x and a being driven independently.  It seems to work well and I assume that it will work in real time.  I have confirmed that each of the two actuators are "geared" differently.  Will Mach allow the slaving of two ratios?  It seems that the software allows it during screen setups, however, when I ran the configuration as x&a slaved the x data seemed to be dominate.  That is,  x moved correctly and a ran away.  Is there a fix to run slaved?

Thanks!!!

It seems to be perfect.

I have a follow up question.  If I am lucky and both actuators (each from a different manufacturer) are "geared" exactly the same and thus could be slaved, can the x & a each have home switches to make certain the gantry always starts the day  parallel?

I know steppers don't ever miss a step, but none of mine got that memo.

General Mach Discussion / Simultaneous of X and Y

I would like to move un-slaved x and y at exactly the same time to an entered value.  The movement is a gantry having two individual stepper drive screw actuators.  I am using the below to move a single actuator and I have been able to modify it to move both actuators, however, when that occurs, the first actuator positions and the second actuator follows.  But, I haven't figured out of to get simultaneous movement of x and y.   

Distance = GetUserDRO(1001)

Code "g90 g0x" & distance

General Mach Discussion / Re: Driver watchdog triggered.
« on: August 17, 2014, 04:05:07 PM »
We connected to the Gecko computer to the problem machine and all seems normal running windows 7 with watchdog enabled.  However, a new issue has come to life with the original computer/config.  That is, in jog mode at approx 150 IPM the movement is smooth.  But when in rapid movement under direction of G-Code the movement is rough, jerky, and stalling.  The same is true, mostly stalling, when machining at 20 IPM.
