Your welcome. If I haven't posted on it in a few days, send me a PM. I forget sometimes.  Not on purpose though.

This is what I get. The reason for the differnet colors is just another good feature of Mach. Do these help?

I don't know this for sure as I haven't seen it. It may make the screen freeze somtimes I think. I have a cheap dell and it runs good. I'm not doing anything real fast though. I think it is a 2.8 Ghz CPU and ran with 256 of ram. This is not advised, just shareing it with you. Also it has onboard graphics. I don't think it has a PCI express slot either. I can let you know in a few days how the new PC does. I have about $350.00 in parts for it. I didn't need the new PC for the mill, just though I should since I need another PC in the office. Mounting the components takes up less space than a midtower.

General Mach Discussion / Re: Unsolicited Pauses Between G00 and G01 Commands?

Sounds like you're questioning my compotence? But why would someone of a thousand posts do that?

Sounds like you're getting rude. But why would someone of 3 posts do that?

Back to the subject.......

The reason I ask is because I have never heard of that being preferred. I use two cam packages and neither one generates code like that. Maybe they should, I don't know. Are you running the code on a machine or just simulating? If you are simulating, did you install the drivers for Mach? Have you tried the code I posted? Did it help? Are the dros pausing as well or does it seem like it is pausing because the accel rates are set very low in your motor tuning?

Just trying to help

How long have you been running CNC equipment? Your post processor could be tweaked I'm sure.

The last bit does that because you have a rapid G0 then a feed G1 then rapid G0 then feed G1. It is going to move you z each time it sees a rapid. Things can be done to eliminat this but it is not advised. Also your code should be G0 or G1, not G00 or G01. If you want smmoth motion at full speed just give it some code with a feed in it that is equal to your max speed.
Something like this.
G0 X0Y0Z0
G1 X2Y2 F 100 (insted of 100, out your max speed)
G1 Z2 F 100
G1 X0Y0 F 100

Good job. What program did you use to generate the code for that piece?

Hats off to Graham for such a nice contribution. Some of you folks will find this very useful if your code generating is limited to Imperial or metric. Men like Graham are one of the main reasons this forum is so nice.

Thanks Graham
