Finished Screens / Re: Mach3 2010 Screenset - Now available

Gerry
I thought I was using the updated macros but it turns out I downloaded the Auto Zero G54 through G59 modified macros instead of the Modified Macros for Chinese Motion Controllers .

Good to go, thank again.

I got it working woo woo!

Anywhere there was a call to GetVar:
Code: [Select]
ZNew = GetVar(2002)
I swapped it out for a Sleep and GetOEMDro
Code: [Select]
Sleep(250)
ZNew = GetOEMDro(802)

I meant GetVar(2002) vs GetOemDRO(85) or GetOemDRO(802)

@Graham Waterworth,
Thanks for the suggestions. In general config, "include TLO in G31" was unchecked, it is checked now. I added a G49 to the beginning of the script. Yes, the script was looking for var number 2002. With those changes, the new retract is still headed to +9.

Can I use GetOemDRO(85) or GetOemDRO(802) instead of GetOemDRO(2002)? They seem to have proper values, though I don't know if these moves should be in machine or work coordinates.

Hey All,
I added some debug info the script. After the initial touch, my machine wants to retract to 9.878.... But 0 it the top of my Z and all the numbers on the Z should be negative. Also, even if 9 was negative, it is pretty far from the machine coordinate of -13 or the work coordinate of -3.2. Based on the DROs it seems the retract should be -13.02... or -3.19...

Is there a way to update the values?

The message in the display is showing the values before the move:
Code: [Select]
Code "G0 Z" & ( ZNew + FirstRetractDist )
Please see attached.

Thank you for all the info. I have been eyeing the SmoothStepper for a while. Come winter I think I will do the conversion. Ill check back next year.

I ran into the same problem. This got me to finally understand and write my own brain. It was simple and fixed my mixed signal probes.

Thank you.

Mach4 General Discussion / nMotion Drivers
« on: September 05, 2020, 11:55:24 PM »
Hey All,
I would love to try out Mach4 without having to do a full overhaul.

Are there any nMotion drivers for Mach4?
If not, what is a good controller card for Mach4?
