I have upgraded my Ender 3 with the following:
V4.2.7 motherboard
Sprite extruder pro
Dual z axis screws
Touch screen
All of these were supplied from Aliexpress and I thought it would be a breeze to upgrade and get the printer working much better than it did out the box. Sadly this has not been the case. Now the upgrades are all fitted I cannot get it to work at all, primarily due to the fact I don’t seem able to find the correct firmware for the various upgrades and if am isalling them in the correct order?
Can anyone help please
