I’ve got a taz 4 with a metal hex hotend. I was getting GREAT prints for a long time. Now that I have been printing a lot (12 hours a day sometimes) more I’ve noticed there have been steps skipped. First it started in the y axis only. Then started in the x also. And even sometimes it happens in the z axis.
I have checked everything I can think of. Belt tightness, turned down speed, turned down acceleration, jerk, etc.
I have been thinking that maybe I need to look into either a new power supply, or a new RAMBO board.
I’ve got one of the squeaky power supplies but it stopped squeaking and now the fan barely runs at all, but the machine operates. I should note the power supply has been weird pretty much since I got the unit. (Bought it used)
Anyway. I’ve looked into lowering power to the steppers as they get EXTREMELY HOT during prints. I’ve tried swapping the motors, I’ve tried making sure the bearings slide smoothly on the axises. It’s definitely not that.
So, can someone tell me how to measure if a power supply is bad, and also how to check to see if my board is bad (I’ve read the stepper drivers sometimes need to be replaced)
Please, help. This is a picture of my latest godawful print. Note they are not always this bad but they have been slowly getting worse despite all my best efforts.
I’m losing my mind.
PS: tried later heights of .15, .2, .25.
All types of infill, rectangular/concentric patterns, I’ve tried fast, slow, I’ve tried all the settings I can possibly change, it’s definitely NOT just a print setting…
