Check to see if its the same component everytime if so check part height . Also check Z0.This setup is in the manual. You say this only happens after maintenance is carried out so when you free the nozzle it doesnt happen again until maintenance is

Shifting? Please describe the "Shifting". I.E. is it centering, sliding to cause shorts..... Most 208s will self center. If it's causing shorts, first check your print to make sure it is on the pads. Next check placement. Another area to check

Check flux penetration and type of flux. How much is solid contents. The solder filling is better under Nitrogen. Check the time (speed) of the nozzle whether is correct. Usually For SAC305 the temperature of bath is 320C/degrees, but only for sel

Hi there to all, I have noticed one of my cp is making very loud thumping sound from the table lately. This noise is only from X-axis not the Y at all. Here are the following things that I went through so far: checked if this was due to lack of lub

Don't try the mecha check yet unless you know how. have you checked the coupling shaft of Y-axis? If it's ok, take a look at the ball screw if it looks like being scratched or something unusual. Also, observe the movement of the machine if you hear a
