![]() It is measured in millimeters per millimeter/second. Now let’s see how to save the values we calculated to the machine firmware. Is there anything else that could have happened? My setupįirmware: TH3D Unified Firmware U1.R2.22 (or one/two versions before it maybe) (firmware is Marlin based)Įxtra: OctoPi (Unsure of version, possibly most recent stable release) Other than starting prints, only used to set E steps and G0 commands before problem showed up.Īs for future prevention of resetting to 95 steps/mm, I realize I just need to re-flash the firmware setting the E-steps to 390 or something. fullstepsperrotation: 200 The number of full steps for one rotation of the stepper motor. If we use a 20t pulley with a 2 mm belt, each turn of the motor results in 40 mm of movement. What could have happened to cause my e-steps to reset? The obvious being resetting the EEPROM, which I am most sure I didn't do. I came to have other issues (like a potential clogged nozzle) so I'm not sure how much calibration is needed as plastic isn't feeding, but I digress. I tweaked the idler tension (since I cranked it tight earlier) and for the most part that seemed to help. Benchy came out with some droopy layers, so I was over extruding. I also use the 16x interpolation and have only 409 my hemera und 427. The calculator will then adjust your steps/mm based on the measured value to. The process is to have a known target you are trying to reach and then measure the actual value. ![]() This same calculation is used regardless of the axis. The new pull request sets the default steps per millimeter to over 800 steps/mm. The steps per millimeter (steps/mm) calculation is used to calibrate the X, Y, Z and E axis of your 3D printer. No wonder I was under extruding, I was only pushing a quarter of plastic out! Sending an M92 I was able to get the E-steps back to where they belong. Hi, I use one hemera und 2 Titan aero on my TC. Lo and behold, my steps were back down to 95. (To the point that it looked like only the infill was being mostly printed despite using the same slice settings on past successful prints.) I looked up under extrusion causes (temp, bed level, speeds, idler tension, etc) and nothing seemed to apply, except for idler tension, which I cranked up.ĭespite being certain that I didn't do anything to reset my step settings (namely resetting EEPROM) I decided that I might as well check to see what my steps are set to. Then, after a couple of days, I had major under extrusion problems. Some under extrusion (or no extrusion) happened here and there, solved by calibrating Vref for my extruder (from 455 mA to ~800 mA). I had a couple of days of mostly successful prints. After installing a direct drive extruder (E3D Hemera) to my CR-10S, I calibrated the E-steps so that adequate extrusion would happen going from ~95 steps/mm to ~390 steps/mm.
