Re: Post Processor help GRBL, Standalone THC, Floating head

I attached a sample job file. Here is the current post processor: --************************************************ --*** Set these values up to suit your machine *** --************************************************ --this is the distance between each torch reference in MILLIMETRES refDistance = ...

Re: Post Processor help GRBL, Standalone THC, Floating head

I'm back to messing with this stuff again and spent a few hours messing with path rules and different post processor options last night. Now I remember why I gave up. I simply don't have the gumption left to lead this effort...too many traumatic brain injuries and strokes to even remember what I hav...

Re: Post Processor help GRBL, Standalone THC, Floating head

@djreiswig I thought that I'd modded that post to add the S1000. Maybe I sent the wrong file? That would have been the only change I made though. It sounds like post modification might not even be necessary though. I'd messed with cut rules but was skipping a step or two and couldn't figure it out. ...

Thank you so much! I will try this as soon as I can get back to the machine. :)

Re: Post Processor help GRBL, Standalone THC, Floating head

I don't have a copy of the job file on this computer and probably won't be back at the machine until next week sometime. I will definitely get it posted up asap though.

Are the examples in the first post sufficient? All that's missing from the g-code clips is the beginning G20 G54 G90 stuff and the M05 M30 at the end.

Re: Post Processor help GRBL, Standalone THC, Floating head

I attached a copy of the current post processor.

It looks like I'm actually going to be working on my stuff for a couple of weeks so it might be a bit before I can get back in there to apply and test changes. I'll work on gaining a better understanding of LUA in the meantime.

Re: Post Processor help GRBL, Standalone THC, Floating head

Sorry for the slow reply. I'm heading over there right now so I'll make sure I get a copy of the most recent post processor.

I'm cutting out the outline for my water table today so I'll post up copies of the as produced and modded g-code.


I really appreciate your help!

Controlling THC/Coolant? Path rule?

With stand alone THC systems, it's nice to be able to choose when the torch height controller is on or off. This is handy on small holes, near the end of cuts, and when decelerating for sharp corners. I posted another thread about modifying the grbl post processor to use M08/09 to trigger a relay to...

Post Processor help GRBL, Standalone THC, Floating head

I've been cutting metal but am still having to manually add M08/9 commands to the gcode manually to control the THC. I'm using the newest GRBL with scriber post and other than it duplicating a lot of lines, it's working well. On holes smaller than 0.500" radius and lines shorter than six inches...

Re: keeping pieces together

Up until last week, I had only done tiny jobs, for testing during setup. Last Friday, the time finally came to cut out a whole sheet. I fought sheetcam for hours trying to get it to cut in an order that made sense. I tried moving start points and shuffling them around everywhere and the first point ...

Re: keeping pieces together

I draw everything that I want cut in a certain order into its own layer. Once I get the drawing into sheetcam, I apply the plasma processes to each layer in the order that I want the cuts to happen. There's probably a better way to do it but that's been working for me.

Re: Grbl problems

I copied the code out of the terminal in bCNC and I think it puts that in there once it imports it so you can quickly navigate between the different cut paths in the code. Grbl doesn't seem to see or care about it though. I'll have to double check on my CAD/CAM computer after lunch but I don't think...

Re: Grbl problems

It works! The standalone THC even worked right out of the box. I have a little fine tuning to do but will be cutting metal all day tomorrow.

Thanks again for your help!

Re: Grbl problems

When I was going through the code to add the THC M09/08 on/off commands and remove the z coords between them, I noticed that there was one line N0190-N0200 that duplicated in the code straight out of the post. Other than that, which grbl seems to ignore anyway, everything works great! If anyone's cu...
