Solved this one. It seems to be all my stepper drivers that are burnt. Took a new one and got x stepper motor running. Looking back at when they could have been damaged/burnt I have concluded below: When I wanted to upgrade to diamond hotend I bought a set with a Arduino Mega board, Ramps 1.4 board and extender board. Even though they, at the store, were informed that my Hictop Prusa i3 systemby DKLeader - General
Still need some help on this - have not managed to get any of the stepper motors up running. I have now measured on the stepper driver : VDD - GND : 4,94 V VMOT - GND : 24 V (my power supply is 24 V) Between potmeter and ground I measured : 0,596 V Best Regards Jakobby DKLeader - General
I have tried with temp above 170 as knew about this interlock - this did not change the situation. The stepper drivers are turned in the correct direction. The motors can easily be moved even when they have received "on" signal. Will try to measure if there is 12 V on one or the other pair of wires. Best regards Jakobby DKLeader - General
Hi, My problem is that I cannot get my step motors activated / running. This being xyz and extruders. Seems they are not getting energized / signal. Following is working: Fans, hotend and heattbed. Sending M119 shows that endstops are working and set correct. I have the following setup : A Hictop Prusa i3 It has been modified with a Rumba board and Diamond hotend. I have installed Marlin softwby DKLeader - General
Hi I decided to upgrade my Hictop Prusa I3 with a Diamond Hotend and because of this also a new board. Ended up with a Rumba board and a "Full Graphic Smart Controller" I have used this guide : http://www.reprap.org/wiki/RUMBA I have finally got to the point where I wanted to test the new setup. Ran into different problems (and still have one) done the road. I will list all the problems includby DKLeader - Prusa i3 and variants
