I guess this is as much a EstlCam question as it is anything. Let me preface by saying that having to design on one program and then go to EstlCam to get a usable code is likely the crux of the problem, but I am not even sure if that is true.
I have gone through the Crown tutorial and have had success with both a Sharpie and with a Vbit. I am convinced that with good code the CNC runs well. For reference, my F speeds for the Crown test are F1270. Keep that in mind.
I Created a simple finger joint box in Aspire and then exported it as a DXF. I opened EstlCam and imported the DXF just as I did the Crown file. I used Ryan’s “Conservative 1/8 tool.” Assigned toolpaths and exported to CNC (.nc) as instructed in the Crown tutorial.
Open Repetier and import the .nc file from EstlCam, again just as instructed in the Crown tutorial. I added g29 X0 Y0 Z0 just after the G90 command and saved the file as gcode. Since I do not run Repetier from my laptop I saved it to a SD card and took it to the Lowrider. Position, load the file and go… It is creeping slow. I mean slow to the point Repetier estimates 68h:51m:55s for 4 panels for a box 12x9. Something is not quite right, right!
In this file the F speed is F14.817.
Now I get that a 1/8 endmill will likely have a slower toolpath than a Vbit, but 67.5x slower? That just does not seem right.
So I have some questions.
- Why is that so slow and how do I change it?
- What do I need to do to eliminate EstlCam from the equation? I have downloaded the Marlin Post Processor file from here (https://www.v1engineering.com/forum/topic/aspire-post-processor/) but still cannot get gcode which will work on the Lowrider.
