content: I just picked up a Qihe QM41 Pick and Place machine. Does anyone have a QM41 (or TVM925) and can share their experience with it or offer tips for adjustment and improvement?I am extremely happy so far with the quality of the hardware, but the softwareis a little lacking. Seems like it requires a lot of adjustment to get dialed in, but I'm sure once it is done it will be very robust. I had a few problems to start off, but Qihe is sending replacement parts. The conveyor isn't very smooth either, probably an electrical problem rather than a mechanical one though. Thinking about 3D printing something to make the belt tension a little better too.

content: The machine is not bad at this price level.For the software you need some time to understand how it works.Basic functionality is given.

(Belt, stepper motors, >=0.5mm pin pitch alignment)+ 4 heads+ 4 bottom cameras+ low price- Software- no parts database- no real part height processing- slow vision processing on HD bottom camera- low feeder count

content: Quote from: AJ Quick on November 29, 2018, 01:00:20 amThere is no nozzle height measurement and because you use 4 heads there is no compensation for each head.The pick and put delay is nozzle related not assigned to feeder. (no individual part settings possible)Please check the axis alignment X/Y is it 90 degrees?

content: Ahh. So more per feeder adjustments would be ideal. I could certainly see that being something they could add in software. Personally I'd like to see a bit more automated adjustment and tuning too.The gantry is slightly askew, as is evident when I align the nozzles to the HD camera. The configuration numbers adjust for that of course.
