Thanks for the reply Brian.

Even if it's using the G55 work offset, the X value should not increment each time I save and re-load the Gcode from the wizard without changing anything? The offset should be constant, or do I misunderstand it.

Thanks

Mach4 General Discussion / Font Engrave wizard X shift

« on: February 07, 2021, 07:38:02 AM »

Hi All,

I'm just trying out the font engrave wizard for the first time.
I position my cutter at the correct XY location and zero both axis before I start.
I set everything according to the video and the engrave works fine.
Problem is that if I then go back into the wizard and reload without changing anything the X axis shifts.
This shift increments each time I reload so the text is pushed further off the bed.
I've put the starting lines of the first and second engrave runs below and you can see that the starting X has shifted by 326 mm??

The machine and work coordinates don't move and I can use G0 X0 Y0 without problem.

I must be missing some reset command but I can't find it.
Anyone got any ideas?

First Engrave Gcode
(Font Engraving)
G90 G80 G49 G55
G0 X0 Y0
S10000 M3
G00 Z1.0000 M8
X-39.5300 Y35.0150
Z0.2500
...
Second Engrave Gcode
(Font Engraving)
G90 G80 G49 G55
G0 X0 Y0
S10000 M3
G00 Z1.0000 M8
X286.7100 Y35.0150
Z0.2500

PoKeys / Mach4 PoKeys57CNC Driving analogue output.

« on: December 07, 2020, 02:50:32 AM »

Hi All, sorry for the dumb question but how do I drive the analogue output 0-10V?

I have the PoKeys57CNC sitting on my bench, not connected to anything, except the USB interface.
If I use the PoKeys configurator I can set PWM on pin 17 and drive the output 0-10V with no problem.

In Mach4,
In Configure\control\Spindle I have set
MinRPM -> 4
MaxRPM -> 24000
AccelTime -> 1
DecelTIme -> 1
Max Spindle Motor RPM -> 24000

In Configure\Plugins\PoKeys
In PoKeys mapping I see Pin17 is Reserved:PWM Output
In the Miscellaneous Tab in the PWM Outputs group, I have set
Enable PWM Outputs -> checked
Frequency -> 20000
Enable Pin17 -> checked
Spindle Output -> Pin7
Set to 0 when off -> checked

I can drive outputs to start and stop a spindle OK but the Analogue output just sits at 0V when I move the SRO slider.
How do I map the SRO slider to the analogue output, or am I just doing it wrong??



Thanks
