Estilcam gcode differences

I’ve constructed a lowrider2 and ran the crown no problem. I fired up Estilcam 11.040 and inputed the 611dxf. Z feed problems.

Opened gcode in text editor and no feedrate for first z move.

opened crown and feedrates on every line.

How do I get estillcam to post process correctly?

I currently have to hand set feedrates but can’t do a 1200 page gcode hand edit.

How did you get the crown code to generate the feedrates on every line?

Sorry for my excitement but am eager to collect sawdust.

In this box, the highlighted check box causes repeating feedrate “F” on every line. Without this checked, Estlcam will guess whether the F is needed or not.

From here

Although I printed out that page I missed that checkbox. Still notice a small problem.

I have tool feedrate for x,y =1200 Z =480 (mm/min)
the max feedrate for x,y =2100 Z =480 (mm/min)
so why am I getting Z feeds F1200?
Thank-you Jamie
Thank-you Ryan

Your third line shows your rapids are okay at 480.

For the Z feed rate it’s in the tool definition for “F(z)”. This will normally be much less than “F(xy)”


I agree the 3rd line is working fine. (I’m cutting softwood and foam so more concerned about weight and resonances in carriage.)

The small problem I’m talking about is after line 3 the Z feeds are same as x-y which is too high for the Z.

I included enough code to show 2 G01 Zfeeds at 1200, or am I missing something.

I figured I would learn how to use the machine by trial and error, but with a conservative adventuring.

I’ve done 1 carving into mdf that worked great but I had manually set all feeds to 480 (search and replace).

Sorry for not being clear in my previous missive.

And again Thank you!

Uninstall and reinstall if you are sure all the other settings are correct. It looks good but passing the wrong value.

Yes I agree, I think this is your problem. This is defined in the box that lists all your tools. 1200 mm/min means you have 20 mm/sec in your F(z) column which is much too high. Change F(z) to 8 mm/sec and you wont need search and replace to get 480 in your gcode. (Or even slower might be better.)

Sir Keymaster:

I did fresh install of latest version Estlcam 11.115.

Brought in a rectangle dxf, holed and pocketed and corner relieved. Gcode was proper all z feeds were as specified.

The problem is the handling of stl files. I brought one in and upon examining the gcode generated from free machining it doesn’t output proper Z feeds.

I realize this is a problem with Estlcam but perhaps you could tell Christian he may have a Z feedrate problem in stl free machining.

@christian-knuell If your not to busy we have two open bugs for you. The one above Z speeds not correct in STL free machining and V carve points are backwards starting from the point not the open pocket at least when using a flat endmill for the roughing.
