Hi,
Does anyone know where I can find the Gladevcp toolchange gui that Michael showed on Youtube please?

Hi mariusl,

there are several toolchange-related videos in my youtube channel - which one you're referring to?

for the rack toolchange, and toolchange with length-probe, see configs/sim/remap in master (this is NOT in 2.5).

Hi Michael,
The sneak preview one. That allow one to move the tool and do things while EMC is waiting for M6 to finish. You had a screen with several TABS and included Les Newell's toolchange fix.

Hello,

I'm quite new to this, but I'm trying to setup my machine with the "toolchange with length-probe" from sim/remap. Run into a few problems. Linuxcnc is on 2.6.0-pre0-3255-gce55978. Fixed a physical probe and it works. Made a simple program:

Workflow is:
1. Home machine
2. Touchoff all axes to workpiece in G54
3. Start program.

Problem with the original manual_change.ngc is that the M73 when exiting the sub reverts the tool length offset (G43) to the state before the sub was executed, effectivly canceling out the tool length offset calculated in the sub for anything other than the reference tool.

Fixed this by changing to M70 in the beginning of the sub, and M72 in the end of the sub. But after M72, I added the g43.1 z[#5063-#1000] . This works good with the above program.

Problem now is that after the first run of the program, I want to change tool, touchoff on workpiece and run it a second time. This time there is problem with the offsets, Z0 after the sub is not on workpiece. I suspect it's because after the first run of the program G43.1 is still in use, and I touch off with this, then sub changes g43.1 and messes up my Z0 somehow. If I MDI a G43 before touching off Z inbetween programs, everything is working. But I do not want to do this G43 manually before touch off every time, sometime I will forget it, be sure about it....

Any ideas on how to solve this I would appreciate.

Best regards
Henrik

Anyone?

Of course, sorry for hijacking, started new topic .

unfortunately that code hasnt found its way into the current LinuxCNC distribution; there are some issues with it and some with LinuxCNC itself which need to be addressed before it makes sense to integrate.

sorry,

Hi h_munktell,

you're right - using M73 is not a good idea here. I have fixed the code in master - hope it does what you want.

Remapping per se does not change any modal state, offsets or positions, so results should be identical whether you do it by calling oword procedures or the remapped code.

A good way of developing such a code is to get it right with oword procedures first, and only then wrap it up in a remapped code.

Hi Michael, thank you for your answers. Great fix in the sub! And I have found a solution to my other problem with offsets, see my other thread I linked to before for further conversation.

Best regards
Henrik
