You probably do not have "Drift". The rotary table and or fixture may not be square. The rotary table can be adjusted. You should have someone who has done this before available to make the adjustment before you try it yourself. You can check the

Chris, Appreciate the response - we set FP to "1" last week but no help. The drift is only in the X as well - the Y is never off. We have tried switching the cards to see if if the problem goes to the Y but it doesn't - stays in the X. As for the b

Once a week seems a little to often in my oppinion, we do it every 3 month. As i se it we do it just to make sure that the sensors and other messuring equipment are showing us the truth and not beginn to drift away. We also have some customers that r

Swapping a servo amp out does not lead to an alignment issue unless the new amp is way out of adjustment. Did you do a "drift" adjustment after changing the amp? Does the axis vibrate badly while moving? More likely is someone crashed a head which

The first thing to do is to change the z-rod. Sometimes a very old z-rod spring will weaken causing it to reject many parts. If it only rejects parts after a nozzle change....you may need to put some super lube grease on the O-rings on the bottom of

Hi, Bob you're right. I replaced the Z-rod and the machine started to go alright. When I examined the head's mechanism I omitted to check the most exposed an delicate part... my bad. The old Z-rod came with the machine, and its slide movement was loc

Are you sure the board is clamping tightly. If it moves during a run this can happen. Before reseting the machine. Go and check your feeders. If they are off the same amount....then the machine truly has a drift in that axis...if the feeders are stil

Hello, Finaly, What was the problem on your Hydra head? Maybe my message comes too late, but my answer might help ... It could be linked to a problem with the Hydra Z motor / encoder. In certain circumstances, the Hydra Z axis is not in the correct

Hello I experiencing major misalignments. I am using a Nichia LED package size@ y=.086,x=0.33mm, with recommended solder pad pattern x.086mm, y=.033. Note here is the kicker the PCB pattern does not meet this requirement. The PCB pad landing is based

I think you may be assuming that our operators aren't already doing that. We need to be able to bypass the interlocks... how do you think our operators make line adjustments? Step the machine, drop the tooling, and eyeball it. That's it. The operator
