After the upgrades, Bottie-bot is moving pretty well. Time to push her a little.
At travel speed of 70, the momentum of the HBP caused it to skip steps in the Y direction, eventually causing the layers to be offset a substantial amount (5-8 mm).
Prior to taking that picture, I tried at travel 40 and feed 35, and it was fine. So with failure at 70, I dialed it down to travel speed of 55.
This experiment also reminded me that I hadn’t oiled the rods after the last time I removed them. Bottie was squeaking a little excessively so oiling and tension adjustments were in order. Now to try some bigger parts.
