Post Processor help GRBL, Standalone THC, Floating head

Problems and questions
1

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, I don’t need the THC. If I leave it on for small holes, it dives into the work. I also need to issue a move to safe Z command after every M05 because if the THC was running and the plate is warping, the system doesn’t know where z is until the next touch off. 0.500" is plenty to make up for the warping and to clear the dross on the way to the next touch off point.

Here’s an example of code that I’ve modified that works:

I’ve probably spent 40 hours studying LUA, attempting to mod the post processor myself, and just trying to add the commands in different places in the code but the M08/09’s just don’t show up in the right place and I can’t figure out the correct syntax. The guys who’s machine this is for bought a sheetcam license about a month ago so we’re not using the trial version. Any help would be greatly appreciated.

If you could post a simple job file, the post you are using, and the code you want the post to output, I can take a look at it. I have been somewhat successful at modifying posts, and would be happy to take a shot at it.

3

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!

4

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.
GRBL THC with scribermodded2.scpost (7.98 KB)

5

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.

6

If you you could post the job file that made that code, it might help me to be able to duplicate the code.

7

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.

A few thoughts on this:
First off I don’t see anywhere in the post where this line would be produced.
N8630 M03 S1000
The only M03 in the post only has M03 on that line. Where does the S1000 come from? Not in this post.

There is some scriber stuff in this post that I assume you aren’t using since you say the M08/M09 are for your THC. I don’t know if that is going to affect anything, but it makes it hard to read.
Also, I think the duplicate moves are caused by rounding. The post only displays 4 decimal places, but the calculations could be different further out. I know I ran into the same thing. I put a rounding calculation in my post to eliminate them.

The “holes smaller than 0.500” radius" should be able to be handled with a cut rule in SheetCam.
For the “lines shorter than six inches”, I assume you mean an entity that is less that 6" in length. Would this include a circle with a radius of 0.95"? Thus a circumference of 5.97" or just straight lines?
There is a variable in SheetCam called entityLength that will give the length of the entity. We could probably use this in OnMove to turn off the THC if it is shorter than 6" or on if it 6" or over. Might be able to do the same thing with holes in OnArc, but I don’t think there is a way to determine if the arc being cut is a circle.
Maybe Les with chime in with some additional thoughts.

9

I would definitely suggest doing the THC control with rules rather than modding the post.
Are the duplicate moves a problem?
If the height between moves is a problem you can change it in Options->job options->Material->Rapid clearance.

@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.
I posted another thread about cut rules and code snippets and Les’ reply makes perfect sense so that’s definitely something I’m going to try right away.

@Les I’ve had a few alarms due to code errors but it’s usually after the machine throws an alarm and I have to go manually remove all the code that’s already been cut. Now that I know more, it’s likely that I forgot to put a G01 in front of one of the lines that just populates the coordinates. The correct process would be to modify the drawing, open it in sheetcam, and make new code, but the guys decided to put the licensed copy of sheetcam on a computer that’s busy doing other stuff, so modifying the code by hand is just much easier.

I’ve decided to take a break on working on my friend’s machine though. The table needs leveled and they really need a water table if they want to cut thin stuff reliably and this machine has been nothing but a pain for them so far so they’re hesitant to put more money into it at this point. I can’t tune the software for a table that’s not physically consistent and have probably spent 200+ hours building the new grbl controller and trying to get it reliable enough that they see the benefit in actually finishing it. I’ve been doing all the work for dang near free, with the deal being that I get to use the table at consumables/electricity cost when it’s dialed. At this point, I’m not sure that it’s ever going to be reliable and I just can’t put any more into it. I’m in the middle of building my own machine too so fighting the learning curve hasn’t been for nothing. Everything I’m learning here will definitely be put to use! https://forum.protoneer.co.nz/viewtopic.php?f=15&t=787

Thanks again for the help!

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 have tried and haven’t. So far, it’s just easier to write out all of the code from scratch.

I figured I’d bump this and see if anyone out there with grbl, a floating head, and stand alone THC has figured out a working post processor yet.

12

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 = 250

–this is the reference feed rate in mm/min
refFeed = 500

–Put your switch offset value here in MILLIMETRES
–Put a sheet of metal on your machine and place a sheet of paper on top.
–Slowly jog the torch down onto the paper until the touch-off switch just operates.
–Zero the Z axis then pull gently on the paper and slowly jog up until the paper slides out.
–The Z axis position is your switch offset.
switchOffset = 1.5

–Scriber X,Y,Z offsets in MILLIMETRES. Do not use inches here even if you want inch code
–Use the special code ‘nil’ on the Z axis to disable it.
–In that case no Z values will be output at all while scribing.
–e.g scriberZ = nil
scriberX = 110
scriberY = 220
scriberZ = 0

–scriber axis. Leave this as nil if the scriber is fixed to the same axis as the torch
–scriberAxis = “A”
scriberAxis = nil

–this is an extra delay added to the first pierce as needed by some machines
firstPierceTime = 0

– created 1/1/06
– Based on plasma1.post


– Modified 21/6/2010
– added option for ‘nil’ plate marker z
– Added support for plate marker tool type as well as tool number based plate marker

– Modified 4/11/2010
– Added: Reference the torch on the first pen down if the plate marker is the first tool used.

Here is the code it produces, which won’t work because it doesn’t add the M08/M09 commands to turn the THC on and off and it also fails because it’s losing the X and Y location before the probe cycles. It’s also calling for probes after some cuts, based on distances traveled, rather than putting the probes right before the start of each cut, where they need to be. :
