What is the problem Peter? See a recent posting on a Y axis problem with the same style of machine. If the encoder is cactus, buy a new motor. Sorry, this is the only solution I know of.

The encoder on the Y axis motor is almost certainly kaput. Debris from the wear of the motor brushes or whatever else can find its way onto the encoder and give an ever increasing false pulse. The axis will start OK but progressively go out of whack

If your sure your drive lines are staying put then it must be the motor. ... odd no servo feedback alarms though. That's why I thought problem might be mechanical. Does the yv84 use servo's? IF yes, then no brushes to wrory about. Don't bother t

The Y-axis motor of the YM84 Series is well known for failures. The bearing between the encoder and the armature fails causing dirt to fall on the encoder wheel, hence the encoder mis-counts. If you re-Origin the machine the problem is resolved for a

Hi Ken, Thank for your advice We suppose that with home position all is OK and ratio is in interval 40-60%.Y axis offset is not constant 5mm or 10mm but change ratio with working time and may be more than 10mm We think that problem is with Yservo mo

Hi, We have problem with y-axis offset at YM84 After setting the ORIGIN machine operate exactly but after sometime y-axis recieves offset bis 5-10mm.After repeated setting ORIGIN Y-coordinat became exact. The same things take place if we operate in W

You could also try some of the 3D MID placement machines - some have dispense heads in with the placement heads, so theoretically you could place on the PCB paste, dispense on the terminals. and place the new part. Yamaha/I-Pulse do a couple: https:

I looked into Fuji but heard some horror stories of $50k firmware upgrades to get older machines to work with latest software. ASM doesn't come off as small business friendly. Panasonic is a possibility, I prefer platforms that don't force you to p
