I’ve recently been experiencing problems with the X-axis return-to-home function.
The print head no longer moves to the far right, and as a result, during the calibration phase before printing, it hits the left wall.
I did some research before posting here, and I cleaned the X-axis, removing the graphite deposit.
I made sure I had graphite-coated bearings, and following online recommendations, I only cleaned the axes with isopropyl alcohol without greasing them afterward, as they are self-lubricating.
I use the K1 for professional purposes; I purchased it in July 2023.
Maintenance is performed regularly, following the manufacturer’s recommendations.
Read it again: selflubricating… what if there is no more lubricant?
I had some layer shifts, I cleaned the axis and the carriage wasn’t moving smootly… so I lubricated the axis with some grease… no more layershifts… Printer had over 2400 printing hours… (used professionly at work).
I used dry lube, no problems since.
Once you use isopropyl, there is ZERO lube. Sliding the printhead back and forth for a bit will help, you will definitely feel the difference.
Also, concerning isopropyl: Use 99.9% ONLY, EVER, PERIOD. Make sure when you take off the deposits, that you constantly use a new rag after each wipe. Stop only when no more gunk comes off.
The iso melts the gunk, so if you are not using something clean, you just smear it back on.
Try the dry lube. Wonderful stuff for this scenario.
The spray on “dry” lubricant. I think you can find both graphite and PTFE for whichever suits your purpose. If it causes any issues, which I highly doubt if doing regular maintenance, you can always wipe it off.
I’m back, after trying various dry lubrication solutions… but nothing works!!
It seems like the printer is doing its own thing!!
I request a return to the XY homing, it works, but then I start a print and it’s a disaster.
I’m completely lost. Does anyone have a “miracle” solution?
There’s def a disconnect there, as I can’t see that there is any resistance when you move the printhead.
What happens if to use the pad to move the X-axis 50mm or the Y?
But, me personally, I’d grab my multimeter and check continuity of the wiring. If you’re satisfied that the wiring is all up to snuff,
Have you recently updated your firmware?
2nd odd thing: Usually, after it homes, pass or fail, you gotta turn the motors off, which you don’t. So, with said MM, pass the current through it to see how many amps are being sent to any of the motors.
3rd: Since it took me so bloody long to get back to you, I apologise. I hate to see someone hanging for an answer.
Let me know how you make out, or if there’s anything I can advise you with
