I want to run this simple g-code in printer.. M104 S250 G28 G1 X80 Y50 Z50 F10000 Any idea why that last line does not work? Heater goes on and it homes but does not move into position (X80 Y50 Z50). (marlin 1.1.9.1)by Hexentric - Experimental
Found solution.. there actually was problem in motor wiring Just cross connected two wires ABAB <--> AABBby Hexentric - Stepper Motors, Servo Motors, DC Motors
Hi, can anyone explain why stepper motor in extruder seems to take only one step? (I heated it above cold extrusion limit) After that it rotates freely. There is same problem in two printers but 3rd printer works fine with same marlin setup. stepper driver is ok, wiring is ok, motor is ok... I also tested E1 slot (instead E0) with same result. setup: MKS GEN L 2.1 // marlin 1.1.9.1 // A4988 (16by Hexentric - Stepper Motors, Servo Motors, DC Motors
well, after changing also hot end thermistors both printers workby Hexentric - RAMPS Electronics
I assume it was heating cartridge. I changed 20A fuse on power in and find that both beds heated up fine but hot ends had problems. printer a When heating hot end one mosfet (furthest from power in) got very hot. Cartridge seems shorted and mosfet is constantly in conductive state. printer b Cartridge gives random R values and printer shows "heating failed" when heating hot end. Mosfet seems tby Hexentric - RAMPS Electronics
Element is under glass and measured R is 1,3 ohm when wires connected or disconnected (same as my few identical/unused heating elements)by Hexentric - RAMPS Electronics
Two of my RAMPS 1.6 boards have suddenly broke (one broke at first run and other broke after printing several weeks) - bed is 200*200 - turns on when connected with usb - two printers in similar setups/same settings works fine - replacing mega 2560 did not help - 12V setup I found that F2 (i assume that is fuse) was not conducting on those broken ones and soldered it close. I also redused bed heby Hexentric - RAMPS Electronics
managed to find one solution here: I enabled #define MINIPANEL and followed steps 1, 2 (V2.1 option) and 4 display and sd works!by Hexentric - Firmware - Marlin
Hi, How is it possible to get following combination to work? BTT MINI 12864 V1.0 display with SD + MKS GEN L 2.1 + marlin 1.1.9.1 Cables are turned 180deg on MKS GEN L and REPRAP_DISCOUNT_SMART_CONTROLLER / LCD 2004 works fine. Only two leds and maybe lcd backlight turns on in MINI 12864 when REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER is enabled.by Hexentric - Firmware - Marlin
