I recently acquired an Ender 3 V1 (yes, one of the originals) and have been using it quite successfully for several months. I decided to upgrade to the dual axis with an original kit from Creality. I have four problems.
To get it to work properly I had to loosen all the screws on the vertical supports because there was a lot of binding and the z axis would not move up or down. Are there any suggestions how to re-align the vertical supports and tighten them down so that everything works???
The display screen changes back and forth between the current menu item and the previous menu item at a 1 second rate. Sometime everything works well with out the flicker back and forth. Other times it does not. the flcker stops if I dicsconnect the new stepper motor.
With every think still loose (see 1 above) the auto home will go through its paces properly…all most. I moves the build plate the the x & y limit switch as normal. It moves the z axis to the z limit switch then raises it and the lowers more slowly until it hit the z limit switch again, then repeats the process three more times before beeping and stopping the process.
Coincidentally, I can hear a fit ticking from the display unit while the display flickers.
Is the cable to the new stepper ran alongside the cable to the display? Is so separate the cables.
Pulses from the stepper may be induced into the display.
As for the alignment you may need to use a square to adjust the frame of the printer. Also check that the carage is paralell with the bed.
Re-routing the display cable solved all the active display problems I mentioned. Thanks.
As for the alignment, I worked out a process for aligning the frame so it works without binding. Everything now works and I am now printing my first item after upgrade. So far, so good.
For those interested, this is the process I used.
Will All the vertical frame loose.
Move the extruder to a high position, I used 190 mm.
Tighten the top bar and verify movement up and down.
move the extruder to a low position and tighen one vertical support and verify up and down movement.
move the extruder to a low positon and tighten the other vertical support and verify motion again.
Auto home and level the build plate.
I should note I noticed that the new axis driver was slightly higher than the other. I corrected this by moving the extruder to a vertical midpoint, disabling the steppers, and manually rotating the new stepper so that left and right side were at the same height relative to the frame, not the build plate.
