Hi Guys, Im having unbelievable trouble setting the duet 3 6hc up with speed control problems. My config.g has the m203 set to 3500, and the feed rate for move button at 2500. so thats the controls sorted. however g0 command run at 82.5mm/s, g1 commands are running at 50mm/s, homing all command are running at 50mm/sec but the feed rate is set at 30mm/min, my home x is set to run at 1800 but its moving at 30mm/sec. i just ran a toolpath set to 3000mm/min and the speed shot up to 58mm/sec
any ideas?

Please mark solved,

@droftarts Ok Im getting Close now. I have brown and white gone to psu, the green wire to voltage out on the pwm converter and the Out9 and gnd pins on the PWM signal going to the pwm input and gnd.

My config.g looks like this
; Tools
; AMB spindle configuration
M950 R0 C"pwm_pin" L0:24000 Q1000
M563 P0 S"AMB 1400" R0
T0

when i try to start the spindle Im getting this error from the console. Id be very grateful if you could point me in the right direction

@chrishamm Hi Chris. i have ordered the PWM converter from amazon. So, as there is no much info online for controlling this type of spindle without a vfd i am literally all ears. so i bring power to the spindle from a normal plug. then ???? I can follow pics if you have them instead of melting your head.

Hi Everyone. I'm in the process of finishing my killerbee 1515. Is it possible to connect this milling machine and control it directly with a duet3 6hc and no PWM?

Thanks in advance
Allen
