This one has no problems with touchoff.

Did you ever click on a button labeled "G-CODES"?

There you will find a meaning of G53

Well, another test, fiddling with width of step pulses (in Motor Tuning), same results.

@Graham: No broken wires. Let me "explain" how the system looks electrically/electronically:
Dedicated enclosure with 4 drivers, power supply and BOB (5 Axis Mach3 Breakout) which works as it should, on input side powered by power supply that supplies motor drivers/motors, on thr output side powered by USB cable connected to computer MB, parallel cable M/F for step/dir/switches/... between BOB and PC.

In case of using Arduino, only Parallel cable is shifted from PC to Arduino (homemade PCB holding Arduino Nano and DB-25)

With GRBL on Arduino, everything is SPOT on.

G-Code, CAD, and CAM discussions / Re: Simple M6 Manual Tool Change

You should then change M6start macro, through which you can skip all unnecessary movements if loaded tool is the same as commanded tool.

In your CAM program you can assign the tool number for every tool that you use.
In Mach3 EVERY M6 Tx will do a tool change routine even if the desired tool is loaded in your spindle.
A little of "useless" movements will not hurt you much, time wise.

It seems that people are too spoiled. When we had computers running DOS, from floppies, on 8086 processor, all was fine, nowadays, AMD Threadripper with ultrafast SSD is "slow"

Last version of OS that Mach3 can run with parallel port is W7 32-bit.

General Mach Discussion / Re: Offset dont add up

Tweakie's laser can be substituted with small endoscopic camera, as I wrote you in other thread.
You will have to edit your screen set adding 2 DROs (for camera offset), two buttons for turning tha camera on and for setting XY zero with measured offsets, contained in extra DROs.

You can find Big-Tex blue toolsetter screenset and modify it, as I did.

An update:
Yesterday I fired up machine again and run the same code, and same thing happened.
Then I unplugged parallel cable from LPT port and plugged it to my GRBL breakout (just a board holding arduino Nano and DB-25), fired out bCNC (as G-Code sender) and the outcome was perfect, several times in the row.
Back to Mach - gaining steps

All tests conducted on thin scraps of MDF, so no high loads on spindle. And spindle is Kress FME 1050 FME-1, ergo no VFD which could introduce noise.

General Mach Discussion / Re: Mach3 experimental inputs circuit protection with opto couplers for HW-356 CB

« on: July 12, 2020, 04:42:53 PM »

As I already wrote, you HAVE optocouplers on inputs of your BOB, something817 (prefix irrelevant).

Here is schematic of your board, or very very similar.
