Got it working. Opened it up and looked at the coils and two had wires touching each other. Not sure if that was a the exact cause of it, but once I put it back together and wired it back up I was able to get it spinning. Now I just need to install it on the printer and calibrate it. Thanks everyone for your help. It is very much appreciated.by VectorRoll - Mechanics
QuoteTrakyan Are you able to spin the motor by hand, or the motor+gearbox? There could be debris in the gearbox thats jammed it up. Another thing to look at is acceleration settings. With a 5:1 gearbox, the motor needs to spin 5x faster for the same output speed (ditto for the accelerations), this might be too much for your stepper and is causing it to skip steps which results in the clicking noiby VectorRoll - Mechanics
I purchased a Kysan 1040229 Geared Stepper with a 5.18:1 gear ratio to use as a Bowden Extruder but I am having issues with it. It is 1.8° with a rated Voltage of 2.4V and rated current of 1.0A. All it does is Click. I can spin the motor by hand and it does light a diode when I do so, so I think the motor itself should be in working order BUT I am not certain at this point. Anyways...

Never mind on last question. I figured out how to change the Pin. I opened up the Ramps.h file and switched the Z-Min pin from 18 to 19 and vise verse for the Z-Max pin. Now my inductive sensor works stopping the motor. Guess I did burn something out on that Z-Min Pin. Oh well. At least I got it working now.by VectorRoll - Firmware - Marlin
I just tested the Inductive Sensor on the Z- Max Endstop Pin and it works for it stopping the motor. Maybe I burned something out that is keeping it from sending a signal from the Z-Min Endstop pin. Is there a way I can use the Z-Max endstop pin as for the Z-Min?by VectorRoll - Firmware - Marlin
Seems my cell phone double posted. So I'll just edit this as my next reply. Well I did have the blue and black wires swapped. I switch them and now I can get the M119 Command to show the Z Endstop triggering when I put metal up to the sensor... BUT ... It still is not stopping the Z Axis from moving. My X and Y Endstop's seem to work. They stop the Axis from moving. Its just this Z Endstop. Iby VectorRoll - Firmware - Marlin
Hmm by what you said I may just have to rotate the plug on the pin. I'll try that when I get home. When I first wired it up & soldered the transistors on I went by what the sensor had listed on the side of it. That was a few months ago. I'm just now getting to hooking it all up. I'll double check it all when I get home. Hopefully I didn't damage the endstop pin.by VectorRoll - Firmware - Marlin
For the life of me I can't seem to figure out the Z-Min Endstop for a Inductive Sensor. I have LJ18A3-8-z/8X Inductive Sensor and it works. I have it wired right and the blue wire is in the Z-Min Pin on my Ramps board. It senses everything fine as the light lights up when near the the bed and all that, but in Marlin It does not change its trigger when I use M119. Nor does it stop the Z-Axis fromby VectorRoll - Firmware - Marlin
I am curious as to lubricating my Guide Carriages. If it would help? If I can? Or if I should? First off I have a Kossel Mini that came with some Chinese knockoff Linear Guide Rails & Carriages. They are not official HIWIN but just a generic brand. they have been running ok since I got the printer but I over time they have just become a bit more noisy. Also I have noticed a little rattle likby VectorRoll - Mechanics
I have just started having a similar issue as what this title of this thread describes. Only difference from mine and the OP's issue is that my drivers (A4988) were already connected to the my ramps 1.4 mega 2560 (MKS Gen_L V1.0) and the printer was printing fine for a while then tonight one of my Steppers started to just vibrate. Basically a back and fourth jerking movement. This stepper was myby VectorRoll - Stepper Motors, Servo Motors, DC Motors

QuoteDust NB The central holes are not centered, its offset slightly on the Y axis. (or the cutout is not equal) eg When you upgrade from a mk1 to a mk2 they give you a tool to identify which side is which see step 7-9 Also 4 bearing is over constrained and makes things worse over 3 bearings Hmm Didn't realize they were supposed to be offset for the MK2.

Can someone tell me the distance from center to center of heated bed mounting holes for the Prusa I3 MK2 Bed Plate?

This is just a query. In the Marlin Firmware it specifically says that DELTA does not invert for the stepper direction. ---------------------------- // Invert the stepper direction.

QuoteDust "physical pullups resistors" are external to the chip and cannot be disabled in firmware OK That makes sense. Quoteo_lampe With a NPN NO sensor you need a pullup resistor to make it work. Maybe you just have the wrong sensor? I am pretty sure the Sensor is a NPN NO unless they labeled it wrong. Honestly I am starting to think the code in my Firmware is just outdated.

I can not seem to get the thing to work with my board. At least in the terms of getting the M119 to show that the signal is flipped. When I send M119 I get only the info I have it set to in Marlin.
