New Need help-No feed rate-Bobcad v 26 into Mach3

Post by racer6 »

Hello. I am new I have built my own cnc router/Plasma cuter table. I have cut wood with very little problem. I am trying to get the plasma side of it going. I am drawing a simple file and posting the code in Bobcad v 26. IN mach 3 it says G00 no feed rate. I have tried to set in in bobcad but the code has no feed rate in it. Not real sure how to set Mach3 up to run a feed rate for the file or if I could even do that. Any Help would be greatly appreciated.
I am lost on this feed rate for Plasma cutting. I am using a Hypertherm powermax 65 to cut with.


Thank you,
BTA Plasma

Mach uses basic G code so a line should look like

G1 F300. X1. Y1.

Will error with a F number but not a G1

So if it looked like this instead

G00 F300. X1. Y1.

Your post is most likely bad

This is the G code. Does the line,
should it have a F after the G00 ( G00 F100 ) Like this. Or line N02 should look like N02 G00 F100 G90 G54 X.8827 Y.9528
Thank you for Helping Me.

You cannot have a F and a G00....you need a G1 with an F (Feed rate)

That does not look like its valid G-Code for MACH. You have to match the POST to the type of control so you need a MACH plasma post . You must not have any form of touch off since its not doing one unless all those custom macro calls are doing it. You have to have the Macros listed in the matching Macros folder of the profile you are running to use them. There is no way to edit a POST processor in BobCAD/CAM.
