Re: Different step per z axis - 4 months ago
thanks gyus for your support. I finally did not manage with marlin and i go to klipper. Klipper is tooo easy to implement this and as far as i can see klipper has more option in general. So just fyi z motor is the front and has 20 teeth that is moving two pulleys with 60 teeth.So in rotation_distance i did 8/3 = 2.666666666666667 . I don't know if that is corrent but is working perfect withoby alfadex - Firmware - Marlin
Different step per z axis - 4 months ago
Hi, i have a difficult question that i have not found any solution yet. I use marln 2.1.2.2 with skr 1.4 turbo.I have 2 different z drivers, with 2 different motors. But i need to change step for Z2(E1) because it move 2 axis with reduction from 20 to 60 teeth, as you can see it is the front motor. Is there any way in firmware or even in eepromby alfadex - Firmware - Marlin

Re: Electromagnetic Switching Toolhead - 3 years ago
You said it hapend when you switch off the ralay . It would be more usual to happent when you switch on, however even if this does not happent when you disconnect electromagnet, i would use SSR instead of relay. Also electromagnet should have free wheel diode and try to shorten as possible usb cable or use one with shield. Which electromagnet are you usingby alfadex - Firmware - Marlin

if you manually run M42 P36 S0 and M42 P36 S1 does it work? Have you try other extruder with SOL1 to see if this is doing the sameby alfadex - Firmware - Marlin

hi thank you,my end stop is front , so i change to Y_HOME_DIR 1. But after that (y home button) does not do anything ....plug it into the Y max endstop plug on your controller.... there is not max end stop at gen7 pcb,(atmega1284p) only y_min i try the same thing for x (for test purpose) , #define X_HOME_DIR 1 and the same ,x_home button stop working edit: i did it.

Hello ,,i made some tests and i notice that steps per meter for x and y are not right. So i made some tests and found that steps per meter are different for x and y axis. So, when i build i receive the error #error "Look-ahead requires steps per m to be identical on the X and Y axis (for now)" i try temporal acceleration but it is like choosing none acceleration ,there is too much stress on tby alfadex - Firmware - experimental, borrowed, and future
Re: Temp head high-low - 8 years ago
Hi Traumflug , I try new software and this very handfull config tool, everything goes fine! very easy everything. I am trying to adjust head temp, it really does not affect printing qualitty but i am trying to adjust head temp oscillating +-2 . i try temperature hysterisys 1 and residensy time around 10 and make some combintaion without any result but I don't really understand what those means.by alfadex - Printing

thank you i will try it when i have free time. My problem is that while in winter i was printing perfectly ,i try to print 3 days ago and filament is like head temp is too high (bubbles on the object)! In winter i print at 222 C.At 218 C was too cold and extruder motor struggling. 3 days ago ,i print some things and was with some small bubbles on it, i lower temp at 214C but nothing change, atby alfadex - Printing

Yes, thank you, no backslash at all, i think i will not bother any more with extruders.I raise temperature until 270 for test purpose for 1 hour and no problem anywhere . No Z axis is no lead screws , it is threaded rod M8. This video is 0.2 layer heighby alfadex - General Mendel Topics

Re: i need a good extruder - 9 years ago
Hi friend, temperature is at 231 degree. I raise it up 240 with a little beter result. I would like to go it further but i am afraid the plastic that is screwed the bolt of the hot end is going to melt.Those two fans are not at full speed, i adjust those with pwm and are very low speed, are used so that heat don't go up to the x-cariage. Even if i turn fans so that face the hot end, temperatureby alfadex - General Mendel Topics
