This is regarding R8A robotdigg soldering machine we would like to
know some technical datas about this machine.
1. Accuracy on X,Y & Z axis?
2. Operation range of R axis?
3. Minimum / maximum solder wire size recommended for R8A machine?
4. Minimum / maximum solder wire feeding speed?
5. Minimum / maximum soldering temperature range?
6. Minimum / maximum recommended solder tip range?
7. Solder tip cleaning frequency if any?
8. Recommended gap between soldering pads to avoid solder short?
9. Is this suitable for 0.2mm (gap between pads not pitch) edge to edge
designed pcb?
10. What is the minimum space clearance required for better soldering
around the soldering part?
11. Is there any restriction of tall profile components around the
soldering part?
12. What is the maximum height of component is recommended around the
soldering part?

I need an x axis belt for a cubex cube duo. I could replace the Y axis at the same time which is prudent. Could I use a generic length of belt with the same width and tooth pitch?

You need a backup belt indeed.

And check the belt situation before a new print.

I agree linear guide is better option for speed and precision than linear shaft, but it's quite expensive than the linear shaft and bearing combination :-)

I am Not sure if the dropping suddenly occur only when power off the desktop engraver or when the Z axis stops.

A. If the dropping happens when power off, then try to consider a brake stepper motor for the Z axis.

B. Stepper motor itself or the auto-current reduction function of the stepper driver.

1. Try to increase the current to the stepper motor and stop the auto-current reduction function.

2. If the 1st step do Not have effect, then consider to change to a nema23 stepper motor
