Easel Ignoring my Plunge Rate Setting on initial setup

Easel
1

Hey Guys,

In easel I set my Plunge Rare to 80 mm/min & Depth Per Pass to 1.5 mm

When I do an Export to G-code (to inspect what is being sent to my CNC) I notice on the third line of code that the F or Speed is 228.6 and there is no way to change this in Easel?

G21
G90
G1 Z3.810 F228.6
G0 X79.577 Y22.299
G1 Z-1.500 F80.0

I am wondering if I set the Z Max rate on my GRLB Controller then this line of code will be throttled? i.e. only go 80mm/min max?

$112=80.000 Z Max rate, mm/min

Thanks Rob.

The third line is only a retraction, 3.810mm up (or any other value you might have set as safety height.)
I dont think you can change that within Easel, nor does it affect you 80mm/min plunge rate, which you see in the 5th line.

Thanks! I do understand that it retracts and doesn’t affect my plunge rate.
Its just that my equipment can’t handle a retraction that quick.

I could change the code manually and use a 3rd party gcode streamer or hope that it acknowledges my Z Max Rate!

Thanks Rob.

Ah, what is your equipment exactly?

GRBLs max rate will be the limit no matter what the Gcode says.

Thanks so much its working as expected with the GRBL Settings changed!

I’ve got an MPCNC with T8 Z Axis, I believe it is messing steps because it is running to fast.

I had a ACME T8 Z aswell, it would plunge/retract fine at 3000mm/min (and 750mm/min*2 for acceleration)
This was with a Nema23 269oz/in @2,8A/24V

Wow that is hardcore!

my issue seems to be fixed by throttling the Z speed

Cheers Rob.

Are you running with a nema 17 ?
