Awesome job with the PP for V Carve. I purchased V carve Pro vs 10 several weeks ago and have been looking for a way to edit the PP. I am a complete novice at this. I did purchase the low rider from Ryan and have had some luck with Estlcam but it has limitations for what I want to do making signs.
I did download your PP but I am having a problem downloading it into V Carve as a PP file. I can save it only as a text file and it shows up in the post p file in v carve when I load it but when I go to save the project and open the correct PP fi;e it does not show up.
Any help you can give me to get the new pp saved will be greatly appreciated.
@john: Thanks for the post processor for Aspire. I did notice something that i think might be an error… or oversight.
At the beginning of a “run” the CNC is supposed to raise the bit to “Safe Z”. In the PP, this command is listed as: “G1 [SAFEZ]”, but the [SAFEZ] variable only gives the number and not the “Z” command. Thus, if your Safe Z is set at 5mm, the resulting Gcode will become “G1 5.000” and will basically do nothing, resulting in deep cuts. I didn’t notice at first, because I sat my Safe Z to 2mm. and was cutting fairly rough cuts.
I guess the right command in the PP would be “G1 Z[SAFEZ]”.
Also, the marlin firmware as far as I know, does not support G0 as rapid move command… we should probably change the rapid move line in the PP to something like “G1 [X] F80 [Y] F80 [Z] F10”…
If anyone have any other thoughts about this, lemme know
I don’t think that would work, it is one speed per line, so you either separate it (G1 X Y F80, G1 Z F10) or you can make sure the combined move from one point to the next would not violate the max speed you want. Usually a XY move is large and a Z is tiny so the z moves at the same time but distributed over the entire move it ends up moving slow enough.
Not sure how to clarify the second part of that but I can try again if you want to do it that way.
Well, I tested it out, and it worked fine. I did change the numbers though… I set them to F2000 on the X and Y, and F500 on the Z…
I also accidently forgot to change the G0 to G1, but it didn’t seem to make a difference… Before changing this line, my CNC would crawl slowly to the first point, but now it speeds to where it wants to start.
There should be a way to set the speed of the G0, Marlin can handle them it just doesn’t treat them any different (yet). So a Rapid speed usually just has to be set within reason Start at 30mm/s XY and 8mm/s Z. You can work your way up from there.
Just recently upgraded to Aspire from SmartCAM, and the biggest issue I’m having at this moment is the post processor for our Komo VR408 with a Fanuc O-M controller. I had a post processor made for smartcam, but when I read the text in the algorithm for smartcam I don’t see how to transfer that. Is there anyone out there that can help me with this? I’m going nuts looking it. lol
I'm stupid. In Aspire when you make changes to the bit's feed rate you need to hit the "Apply" button to make it update the project with the new speeds.
I was using waaaay to fast speeds, the post processor was working exactly like it should.
Nope. I would say just excited to get to the action, making an idea into reality is always cool as heck! Trust me, this sort of thing will happen all of the time. Glad things are working as they should.
Hmm… when I start the print, the Z-axis moves up about 3 inches before moving to the X/Y coordinates and cutting in the air. I’ve tried the first post processor file and the one from 12/8/17, as well (which doesn’t move up as much but slowed down to a crawl).
Any ideas on what the problem is? I might try what another user here said and just output it as a DXF file and then use estlcam to go from there until I figure out the issue.
