Re: Poll: Acceptable lost steps?
Zero lost steps.
If you are losing steps then at some point you will have a major loss of steps and break a bit or waste an important part.
I used to be in the design it well and open loop steppers are fine camp. Then I had a stall during a rapid on an important part, broke the bit and caused a lot of extra work. Now if I was building a new machine I would use closed loop steppers at minimum.
Yes I was running close to the limit of the machine, but I'd run it with those settings for years without an issue.
