I think with the pwm from the mosfet and the dc-dc the signal wasnt "clean" enough anymore so the spi got interrupted cause its pretty sensitive. I just used a mp1584en breakout.

Cant find anything out of the ordinairy in ur config at first glance... Have heard a lot of bad things about the chinese TMC's though, so this would be my first guess... In case ur not finding a solution i could send u a genuine TMC from Watterott w…

In case anyone still needs help (and im actually able to help ) im probably availiable tomorrow around 13-14 o'clock, as said ts would be easiest for me. Just msg me.

Thats just G1 Z380 .

@alexsomesan Short question since im not near my printer to test, is M906 to set motor currents working in repetier?
-
Might be able to join in, Teamspeak would be easiest for me. Located in Germany so timezone should be the same. Mine are working by now still got to test around a bit, since i usually get steplosses on the "back move" after homing but i guess that …
-
Alright if they are stock they should be suiting the printer. Just for ur understanding Nema 14/16/17 etc. defines the dimensions of the motor i.e. Nema17 is 42x42mm but the other values may vary. Try the following: Set #define MOTOR_CURRENT { 900…
-
Well the only thing u stated about ur motors is Nema 17 which literally only defines the dimensions of the motor but doesnt tell anything about torque, currents and so on... Anyway if ur running stealthchop, ure probably only able to run it at pret…
-
No, in most cases stepper motors lose torque when going at higher rpm's. In addition ur board has to calculate twice the steps, so u might run into additional trouble. What are ure current motor specs? (Holding torque etc. ?)
-
Humm, maybe try to clear the EEPROM manually and reupload?
-
@alexsomesan Yeah its 24V - 5V and since i always got some of those little MP1584EN around i used one of them, didnt know they would interfere like this. But gladly i got Mister @RAyWB to teach me and tell me how shitty my electronics look xD
-
@alexsomesan got mine working by now, looks like my dc-dc-stepdown on the extruderfan interferred with the SPI, now with going straight from the powersupply to the mosfet and a added capacitor erverything works as expected
-
Ah forgot to mention in case u should not be able to reproduce it, i got another radds in my sls-printer which i could test. But im not in a hurry since the old setup still works. Thanks anyway for ur effort!
-
Tried pretty much every mosfet output except the one for the heated bed. Right now its on heater 2 (pin 12), settings are #define EXT0_EXTRUDER_COOLER_PIN ORIG_FAN2_PIN#define EXT0_EXTRUDER_COOLER_SPEED 255

Using the RADDS board. https://imgur.com/a/iheXb

Short notice, replaced the 2130 with the old 2100 and uncommented the 2130 section. Like this everything is working as intended. So i guess somehow the SPI communication is blocked when the extruder cooling fan triggers?!
-
Okay i tested pretty much all mosfets and it seems as soon as the extruder cooling fan triggers the x and y steppers are disabled... Power supply is sufficient. Could this be a firmware problem, since if i trigger for example the partcooling fan on…
-
Okay i think i found the problem, i think something on my board is wrong. As soon as my extruder fan starts the x and y are disabled. When temp is below 50°C and the fan turns of i can reset and move the axis again. Ill try to pin the fan on anothe…
-
Nope i disabled it for testing, feels more like the drivers "losing their head" u mentioned before

Okay, homing works, but the problem still exists. At first i can move the Axis. When i start a print axis arent moving (except Z and E, still TMC2100). When i stop the print i cant move X and Y anymore. After something like the 3rd reset i can move…
-
Oh yeah of course, ocassionally im a little bit stupid, sorry I wanted to test the sensorless homing.
-
M119 only shows the Z-Enstop (Hardware Endstop)
-
Nope, i guess its some endstop settings. Is this correct? // ################ Endstop configuration ##################### #define MULTI_ZENDSTOP_HOMING 0#define ENDSTOP_PULLUP_X_MIN true#define ENDSTOP_X_MIN_INVERTING false#define MIN_HARDWARE_END…
-
Hmm, i got some strange behavior, i can move the axis manually, but when trying to print they are not moving. Not using Stealthchop or anything...
-
Alright, looks like its working for me with the development version!
-
After using ur Youtube as a chat i found the Thread now too Have the same trouble, I will try to switch to development. Sven

Alles klar, klingt gut

Yes its a powder based system. Hardware is Due/Radds. Should be working im planning to only use dark powders or mix white powders with industrial carbon. Im going to preheat the powder therefore the laserpower should be high enaugh. Adjustable powe…

Hey RAyWB, thanks a lot for offering ur help! Im pretty new to the laser topic so excuse me if i mistake some things... Im builing a SLS-Printer using a 2W 445nm Diode-Laser from Lasertack with the linked driver and a radds to control the whole prin…
