I presume you mean 1000mA and 1200mA (1A and 1.2A). Normal motor current is between 60% and 85% of the rated current of the motor.
Yes I ment 1A, forgot to remove the milli after the conversion. I've increased the current to 1.3A but it had no effect on the pattern.
I suggest you check that the carriages run freely up and down the towers when the rods and belts are disconnected. Unless they are extremely light, they should drop under their own weight.
I use the typical kossel carriages and they did drop of their own weight until i tightened the horizontal screw through them to lower the chance of warping in the Z-axis. It might not be needed anymore since I switched from the traxxis rods i used before.
Lubricating the magnetic ball studs may also help - I use silicone grease on them.
Gonna go get some tomorrow to give it try.
wouldn't build a KosselXL again with 2020 and use 2040 instead, which extrusions are you using?
Oh I'm using 1515 rods, which is one of the reasons i tightened the carriages. The carriages is printed in PLA and from what I recall the "handle" didn't flex that much but since I have a horizontal screw through it it cannot flex that way while assembled.
