I have read the documentation but still unclear.This is a brand new build using the SKR Pro(Cutting area 24x24) and would like to be able to move the router and cut a little faster.
I’m not looking for records cutting speeds. Based on experience, what is a good happy medium?
I saw this command in the doc, which states it would give me 30mm/s
M203 X30 Y30 Z10
So hwre it is, IT ALL DEPENDS, sorry i just wanted to be the first! There are soooo many variables, you will need to test!
Depends on size, pla or other, how tall, your router, what bits, and on and on. I almost trashed my mpcnc recently. Oak made sever chatter. My machine is about 3 years old and it still made a chump out of me.
I always thought the bigger badder cutter would win, but ryans small 1/8 cutters are the best i have. (And i work at a cutting tool suplier).
So, pull up a seat, because many great peeps are here and they all like to help. Welcome, enjoy, and ask questions, but please when you do, post pics, what you have and how you experienced the problem you are having!
Just to be clear, M203 sets the maximum federate, not the current federate. So if you author higher feedrates in your CAM, this command will limit that federate. Also, if you execute M203 and follow it with an M500, this maximum federate is saved for all future jobs.
Personally, I have a conservative maximum federate but will put an M203 at the top of specific jobs where I want to run faster, like laser engraving or when cutting foam.
If you want to get an idea of how fast some people were able to run their machines, search the forum for “drag race” or “speed test.”
P.S. Word of caution. M203 takes values as mm/s where most other places in g-code, the values are in mm/min.
Nice Catch!!! See I told you others would be along to help!!!
do you know where you saw this at, based on Roberts answer, i want to see how it is worded.
nvm, found it. It does state “Max Speed”

Hopefully you did not save after making this change. You should get your settings before making any eeprom changes, so you change them back if you need to.
I did not make any changes yet. How do I get my current settings?
@robertbu you may know better, my research shows m503 list eeprom, am i correct?
Yes, M503 reports your settings. I’m assuming he is running Marlin. Note that if you make changes to settings using g-code, then any changes made directly in the firmware will be ignored. This is designed functionality so that when firmware is updated, the user changes don’t get lost.
As for the firmware for the Marlin Primo, V1 has the following default max federate settings:
#define DEFAULT_MAX_FEEDRATE { 50, 50, 15 }
So, the default is 3000mm/min for X and Y and 900mm/min for Z.
For my machine, I could do certain parallel toolpaths in foam at these speeds, but was too fast for harder materials. I run my machine at 12V, so there is not much torque left at these speeds. YMMV.
