M143 H1

Thanks for the suggestions. I figured the problem out I have to set the temp 1c higher than what I want my max to be in my config.g file.

@thomasthetrain
I've printed with M579 and this is the result, now the 80 mm is perfect but still not the rest.

thanks for the tip but because the differens in dimentions is not linear i can't apply M579, ( I Think )

Well if it is non-linear that would lead me to suspect a hardware problem.

Those steps/mm numbers are correct so it must be something else.

You have the stepper currents set to 800. The would be appropriate if the steppers were spec'd at a max of 1000. Which doesn't seem likely.

Try upping the current to a max of 80% of the stepper rating. Maybe the steppers are just missing a micro-step here and there.

And the max speed setting of 180,000 seems rather high - that works out to 3000 mm/sec

Oh yes, one other thing - always put the M92 command before the M350 command and be sure the M92 command aris correct for X16 micro-stepping.

If you do that you can then change the settings in the M350 and the firmware will do the appropriate calculations for adjusting the steps/mm.

@westech Increasing the Z offset gets it closer to the bed, decreasing is farther away. I added this as a comment the the G31, so I wouldn't forget.

@nick9one1 You might find the input shaper plugin a better way to understand the options. https://docs.duet3d.com/en/User_manual/Tuning/Input_shaping_plugin

@bubblevisor I thought about focused cooling at one point. Using compressed air (from an air compressor) and a solenoid seemed like it would be worth a try. If you already have a compressor its pretty simple from there.

@caveman Are you activating Tool 0? There is no T0 in your config.g. See https://docs.duet3d.com/en/How_to_guides/Commissioning#h-5-check-heater-functionality

Note RRF does not allow extrusion if the tool temperature is below 160C. If you have no filament loaded and want to just test motor movement, first send T0 to activate the tool, then send M302 P1 to allow cold extrusion.

If it still doesn't work, send M98 P"config.g", and M115 for the firmware version, and post the response here. Also check that your firmware version and DWC version are the same.

distance from bl touch from x0 y0 so i won't be able to probe right on the screw

You don't need to be able to do that. Just get as close as you can.

When the firmware knows the locations where the bed is being lifted and where it is being probed it can do the math and get it all to work out.

This is the relevant information from my printer:

M671 X-180:0:180 Y-65:130:-65 S3 ; positions of ball studs ; --- probe near ball studs --- G30 P0 X-145 Y-65 Z-99999 ; probe near ball stud #1 G30 P1 X0 Y100 Z-99999 ; probe near ball stud #2 G30 P2 X145 Y-65 Z-99999 S3 ; probe near ball stud #3

@matej1006 spot on

awesome ok thanks yes i did start to loss my hair 😉 thanks

Im using the exact command you given me, M303 follows by the T0 and i am using S200 as its my most common temp

@stephen6309 That worked a treat. Thank you both for your help 🙂 you are real human beans.

Well as this isn't an actual Duet product and I'm not really familiar with the Troodon boards I can't really venture to say what to replace. The board maker would be the better place to ask. Just speculating you might be able to replace the driver chip if you have that kind of hot air rework capability.

@phaedrux well damn i see what is happening there are pre saved values in config-override.g, it is doing what it should overriding my config. 🙂

@nightowl999 well looks like if you have a ups module you can manage the power recovery very well even without M911. in trigger file you can pause the printer or cnc with G25 and it makes sys/resurrect.g
after that you can just recover with m916. I will write guide if it works, I think you can use it. those ups are very cheap.

@braeden-0 M104 is working btw.

Slice's published numbers for Magnum+ printing ABS were 91mm³/s, printing at 300°C, 60 degrees above the manufacturer-recommended print temperature (53mm³/s if printed at the recommended temperature of 240°C).
CHT nozzle supposedly gives 30%+ higher volumetric flow rate (probably more for a 1.0mm nozzle).

Super Volcano claims a max volumetric flow rate of 110mm³/s.

@dc42 I have seen a stl that supposed to show ringing. seemed very long process. which method is more effective in your opinion?

@dc42 thanks for confirming. What happens on a CoreXY system?
