Open the .nc file in note pad or another text editor. I use sublime text myself because it’s geared towards programming. Right after the first G90, should be line 8, type G20. Save the file, and then run it.
That’s the best work-around until a proper post is made. It’ll be tedious to do that for every program, though.
I guess I should clarify, you should really download the program and try it out. You can modify the behaviour of the program extensively. I’m just not very well versed in all the gcode stuff. I already have a sub-program for the Maslow based on the GRBL profile established and saved. It doesn’t appear in the menu but I open it when I open the program and it applies that profile to whatever I create or work on. When I have time I will probably be able to figure out how to get it to show up in the menu.
thanks for your purchase we emailed you the license key.
Yep I got it thanks!
if you are using webcontrol, you can edit the gcode from the web page when you upload it to add that line.
Try going to Setup->CNC Program Settings and selecting GRBL as the processor. You can change the units used as well. They default to mm & mm/min (which I think is correct for Maslow… someone correct me if I’m wrong). You can change it to inches & inches/min.
I think this will be fixed using GRBL as the processor and making sure G2/G3 is checked on that page. From what I hear, the author is very helpful, responsive, and likely would be happy to include a Maslow processor to it.
That is what I did, I need to do some more digging to see if I can change the precision/resolution. It ran a lot of code but the Arduino seemed to handle it fine. I apologize for being so non-systematic I am in a crunch to get this project done so I am just trying to find a way to get it done on time, with as little distraction as possible.
I’m liking Estlcam so far. Only a couple of simple projects so far and the output works as long as I have the units correct.
I did get one were the cut program that was at least 2X ths size of a plywood sheet. I clearly made an error in the import settings. Easily fixed by loading the drawing file back into EstlCam
2x? Maybe 2.54x…
That would be a metric/imperial issue.
Joined the EstlCAM crowd. My Maslow is being guarded by the swamprats in the snowbelt while we’re enjoying 80F days so I’m staying amused with a grbl controllered 3018 router that’s about 1/50th the cutting area of a Maslow and works happily with EstlCam. Don’t expect a key until after the weekend, but decided order it now than procrastinate, forget, and miss the sale.
The key was emailed within a few hours, but the swamprats must not be fans. It ended up in the spam folder and I didn’t notice until last night.
Guess I’ll have to find a 3D swamprat model and 3D carve one (my dinky router will do that!) to appease them. Might be hard, they’re camera shy

Ive been using estlcam with my maslow since november. I have been VERY happy with its ease of use, performance and capabilities. manual mode for part and hole creation allows you to use some exceptionally terrible svgs and dxfs. getting rid on the 102 sec wait on my nag screen is WELL worth 40 dollars.
got my serial already!!! im stuck at work for 3 more hours.
if you are new to Estlcam i highly recommend two things:
the english youtube videos from the creator. (https://www.youtube.com/watch?v=adD7EVfmEXA&list=PLqskLEz9H24T6kSPnQlbMIYHTe0fnfQUA)
and a nice trackball.
those things totally fixed my frustration level with this part of my toolchain.
Is your milling moving at normal speed, gcode files produced in EstlCAM are huge and very slow on the Maslow for me. Do you have this problem, if so, how are you handling it?
Please and thanks in advance.
there was a discussion on this recently and a new machine profile created for
the maslow that at least partially addressed this.
the problem is that it’s making lots of tiny movements and the overhead of
processing each line of gcode is slowing things down.

A profile made by the designer? Where can I get my hands on that?
I just updated to the latest version of EstlCAM dated 2/17/20. I don’t see any reference to Maslow in the program controls.
This wasn’t something in EstlCAM download, it was on one of the Estlcam related
topics here.
