Ever need some extra support for your oversized payload? I got you covered.
I’m working on some suspension for my 80mm spindle. I haven’t fully gotten this machine working, but I didn’t think it was right to ask a stepper to hold up the 11lb behemouth by itself. I thought I’d bring in a 15lb gas spring.
I haven’t designed the tool holder yet, but here’s a picture of the Z-Axis supporting the spindles weight without the help of the stepper.
More to come.

Cool. I have a few spring assist tool holders they are pretty cheap and have a decent consistency to the load handling. That is much cleaner though.August 14, 2019 at 8:19 pm #109683
Pretty much there!
Designed the spindle holder! Couldn’t use the original tool holder due to clearance.
Ryan: This is a spring assisted tool holder. The purpose would be to give a counterweight to a heavy Z load. Without the spring, the single Z stepper has to lift this huge piece of metal all over the place. I’m thinking I can get some faster z travel with this and maybe run that stepper a little cooler (Idk if that will be an issue anyway).
Also, if I cut power to the machine, the Z-Axis stays in place and doesn’t crash into the workpiece.

That is cool!August 16, 2019 at 7:23 am #109818
How does it work? That looks to be a very small Z stepper so if it is doing even normal speeds with that large spindle you did good work!
Great idea for sure.
