I’ve been running some material called Sikablock M330 recently, which is a hard polyurethane tooling board. I did one job, which went very well, then the customer requested something similar, but bigger. I ran it today and I’ve destroyed two big pieces of it…
One side went fine, then on the other the machine skipped about X-100mm and ploughed through it. I swore a fair bit, checked a few things and re-ran it, but this time it didn’t even make it through the first side: it skipped X+ maybe 100+mm and gouged out the stock.
I did notice a LOT of static around my vacuum on the first run, so took it off for the second and just vacuumed manually. I also had a wire from the hose to ground (literally) but it still failed. Belts are definitely tight, stock didn’t move.
Do you think I should be looking at static as a cause?
