dwl is right. You just have to spend some time to play with all the ones that causing the most delay. I would say the timing for X & Y axis try to set to max speed first (as long as not drops before placing). Then, slowly increase the Z speed until

Hi Spoiltforchoice, you are right. I tried to download and setup the PCB Artist as you said. The pcb file is really designed by it, and I opened it, but unfortunately there is no any gerber output option. Maybe this sw is only used to design some sim

Pin holes in the solder joints on various devices can be an indicator of something amiss with the solder paste itself. Solder paste storage may be a concern. Do you possibly have someone putting paste back in the refrigerator after use? Are you tr
