@Ellis Would you be open to me using your script on my website to replace the current one ? www.advanced3dprinting.com is my site . Or i would love to have you post a blog article and you could put a tip link in it since i do get about 700-900 unique visitors a day so it should get you something in return .

@dc42 Ohhh thankyou i did not know that i was just using the info from my generator and my well pump starting load vs running load lol

@dc42 and @Phaedrux and @bwnance please correct me if i am wrong i am going to be adding my ez out switch now to as i was under the impression the 1 amp plus 50 percent for start was still ok for the mosfet on fan0 but anyway i plan on swithing to a brushless pump anyway as i found a kvp8 pump that flows a large amount and can run series or parallel.
I run berd air as well and two things the pump is very noisy it actually can make my camera get artifacts from the emi. Also if you remove the flux ring you will increase rpm as we are not running a high pressure system. Last why are you using a heater block oyu should be connecting 24v constant to the ez pwm board then use the fan output. The only time you would do what you listed would maybe be with a brushless motor that has built in controller and you wanted to run 3wire or try and run a 4 wire with tach but in that situation i would think you would use and endstop output to pwm control the brushless pump so that it only gets 5v unless you want to run all fans at 5v. I say that cause most things do not like the 24v pwm control signal.

@Veti You did not read the thread i assume lol

@nomukaiki The prob is the stallgaurd pin is not correctly routed its a hardware prob that can be worked around in source code i am sure but you would have to compile your own version

@Phaedrux k i installed klipper and had two things one is i found out that its reading the stallgaurd as short to ground on coil b so it is something with teh way the external steppers connect the diag pin or maybe diff sense resistor. so should be able disable the sg registers and then would work i think . And the other thing is do you knwo what pin the mcu temp is on cuase in rrf its predefined but i don't know if its spi bus or if its just a themistor on a internal pin ?

@arhi it is not universal you need to tune it or you can even use an accelerometer to provide the feedback you need to set the frequency and dampening level

@PCR Thanks i have been using it for a while but my klipper printer uses input shaping which is much more robust instead of limiting accel at certain frequency it can have multiple freq and also does not alter accel profile at all so no speed loss or issues with corner rounding etc.

@Phaedrux Do you know the safest way to install klipper ? i am wanting to go to genuine duet wifi and run klipper for input shaping . or will you be adding input shaping anytime soon to rrf?

@pixelpieper it def seems perfect it is more in line with duet 2 imo right ?
