Having problems with slow rapids in estlcam.
I’m trying to drill a series of helical holes in a new spoil board basically a 4x3 grid of 8mm holes. and a trim around the 48x24 perimeter
The job is taking 45mins plus because of slow rapids between holes and I cant figure out why.
I have Rapids set to 6000 on XY and 400 on Z but they seem to clear when I go back to settings page.
It takes it almost 2 mins to move between holes which is crazy slow.
Any ideas? Gcode is attached.

In Estlcam, click Setup, CNC Programs, Coordinates
Make sure that under “F” both “enable” and “repeat” are checked.
Enable means that you use feed rates, Repeat means that you should send the desired feedrate with every move command.
Marlin still wants the “F” defined for G0 commands, which you are not getting. This will result ins a slightly bigger file, because the “F” parameter will be sent with every command, but you will get the feed speed that you want.

Yeah that was just me flailing on the issue. It was correct before I started smashing buttons. F resend is checked again. No change in speeds though. It should be noted that the issue exists in both the ESTLCAM preview and in reality.
I think the problem line is the G00
G00 X585.5250 Y25.4000 Z5.0000 F6000
which should have it flying but instead it crawls. Here is the gcode again

I’m not sure about the details, but it seemed like enabling rapids increased the cutting speed. I never looked into it, I just disabled it. Did I jinx or misunderstand something, or has others had the same experience??

For this, it looks like you should be limited to the max travel in the firmware for the initial move. I think that the V1 firmware has it limited, but I can’t remember the default.
The actual helical drill operations are at a feed rate of 180mm/min (3mm/s) which I would find painfully slow.

I’d think any move with a Z component is going to be limited to the slower Z speed.

Yep I’d expect that but even the G00 XY with a high feedrate is slow
