When we had a line that ended at an older reflow oven without SMEMA controls, I ran a momentary switch to the two pins in the connector. I push the button and the conveyor pushed the board onto the edge-hold of the oven. As a joke I labelled it "LA

DEK248 squeegee speed can't be controlled. It always moves with max speeed or something close to that, regardless of the current settings. Does anyone knows how to fix this?

Looks like it was the diode inside the encoder. Are getting a new printer instead. Did a short time fix, connected a power supply to the motor and controlled the speed that way.

I'll double check tomorrow but I don't think so, it fails zeroing straight away (without moving the other parts) when the PWC axis is enabled, which is why I tried swapping the board as I assumed it was a controller not being found issue.

It can also be a faulty servo controller (not the amplifier), I think it's UMC3 board in slot 10

If your current problem with the conveyor speed was caused by the SMEMA issue, maybe you have a Board #1 problem. The SMEMA communicates to the computer through Board #1. The input signal from the speed encoder and the output analog voltage to the

I need advices as to how a gap between the bottom of an LED (1209-package) and the PCB can be controlled on a small rigid-flex PCBA? The problem that we experience is due to tight tolerance in the design of our molded housing in which this PCBA is as

Are you able to glue them on using SMT glue before reflow?

Thanks Chris for the valuable experience! We'll try the stencil and see what the result will be.
