Question would this line mean that it would use the last Feedrate number as the movement speed which would be F500?? Cause it seems like its moving at 500 not 2100. But I dont want it to plunge that fast obviously.

Sorry to keep bumping this thread its bugging me lol. 


G0 X-74.131 F2100 Y-4.585 F2100 Z5.080 F500 (Rapid Feed rate goes from 2100 to 500 for x/y and also Z?)
G1   Z-5.080 F381.0 (Feed rate plunge speed drops down to 381)
G1 X-72.842 Y-5.619  F762.0 (feed rate goes back up to 762)

Older firmware that feed rate is sticky and uses the last one listed, newer firmware can use separate G0 and G1 rates but I do not recommend it at all because we need separate Z as well.So you need to have a feedrate on every line, I thought my PP had that?

Again you are one of probably 3-4 people using this software and PP around here so you are going to need to have some patience for answers from me. I have no way to test it so I am just guessing.

I highly suggest using estlcam unless you have to use some special vectrix feature. Estlcam works for 99% of the jobs and is proven. Unless you enjoy troubleshooting, then give me some time to get your questions. I answer in the order they are submitted and last responded to so bumping it makes it take longer to get to.

I grabbed the v5 PP from this site named [attachment file=121715] and as far as I can tell it does not list the feedrate with every line, At least on the stuff ive ran. Its not a big deal and I wasnt expecting you to be soley the one answering, I cant imagine the insane workload you have. Worst thing that happens is my rapids are slow. I just find ESTLCAM good but not nearly intuitive enough for me and also im new I screw up a bit with no Undo its a major pain.

Undo is actually pretty easy, use the select tool, pic the bad path, hit delete. If there are multiple paths it lets you pick.

I am not sure how to add it to every line if it is not already there, I was pretty sure I had that working. Is V5 the newest in that thread?

Yeah looks like Marlin_mm test5.pp is the newest one in that particular thread. I cant remember now but does ESTLCAM put in the feedrate with every single line? It will make the last stated feedrate the feedrate of all rapid movements for a G0. When I get home tonight ill have to run it with and without that last F500 see how it moves.

 

I think that maybe because it posts the rapids like this:

G0 X-74.131 F2100 Y-4.585 F2100 Z5.080 F500

I am getting the feeling they changed the software. The only reason I make any PP changes it to get feedrates on every line. Stacking them in a line does not work either.

Do they have a list of PP on their site or anything? Marlin, Reprap maybe?

What post processor are you using with f-engrave

I don’t recall using a postprocessor. I think it generated generic gcode that worked with marlin directly. I might have added G92 to the file manually or something like that.
