LowRider v3 strut plate gcode problems

LowRider CNC Troubleshooting

Hi, getting there with my LR3 build. I have a successful crown test but am flailing around trying to do my first cuts, making the struts.
I have adjusted Ryans sketch in fusion, loaded it into estlcam and set up the toolpaths.
Loaded the resulting files into Repetier Host and ran it on my skr pro v1.2, things start happening, I get initial Z axis adjustments, then nothing.
I tried loading the gcode onto an SD card and the same thing happens.

I have tried just manually going line by line on the gcode and this seems to work fine so i’m at a bit of a loss what is going on. I have checked the settings in both programs and everything seems set up ok.

here is the start of the gcode, hopefully thats of some use

Please let me know if any further info would be of use in getting to the bottom of this issue.
thanks

This F number is in mm/min. 3mm/min means it moves really slow.

You estlcam settings aren’t right. Take a look at the estlcam basics and make sure the gcode units are mm/min.

Have you tried the premade gcode from the test crown? That is a good way to check out the machine and make aure everything after your computer works. Once that checks out, you know to look at the gcode for problems like this.

thanks Jeff, that was indeed the problem. Switched laptops along the way and not set things up properly the second time around.

Hopefully onto making some mess soon.
