Re: Seek and Feed rates, depth passes

Thanks for all the tips! Interesting point about the acceleration values. Is there a way to just make the Z-axis go up and down slower, and the X/Y accelerate and move quicker? I bumped up the speeds and the X/Y were moving very nicely, but the speed of the Z scared me a bit. Haha! And that was with...

Re: How to increase Z-Axis range?

You really need that bottom bearing block. Otherwise the whole Z axis is only held on by the clamping force of the coupler. I have some new DW660 mounts and a modified bottom bearing block that work together to allow full movement of the Z axis. PM me for details. I supposed I'd left it off because...

Re: Grinding on dual Y-axis

After some more testing, I increased the seek rate up to 2000mm/min up from 1000mm/min. The grinding seems to have gone away. I think it was just the sound of the belts at the slower speed, and it's louder because 2 motors are going instead of 1. Seemed to fix the issue.

Seek and Feed rates, depth passes

I'm just getting my shapeoko underway. It has a table size of about 40x24" with a Z clearance of 6-8". DW660 cutting tool, Dual Y drive, Dual X makerslide, aluminum spacers throughout, and new motor mounts, etc. Using high current DRV8825 drivers that are heatsink and fan cooled. Full 80/20 T-slot t...

Grinding on dual Y-axis

I have a dual Y-axis setup. Both motors appear to function properly. When moving the Y-axis, there is what appears to be a grinding sound on the belts, almost as if the motors are having a hard time turning. The X-axis is almost whisper quiet when it moves and the Y fairly loud. Despite this, the mo...

Re: How to increase Z-Axis range?

Here are the pics. All I changed was a longer ACME lead screw and longer piece of makerslide. Measuring right around 5.5" of Z clearance with a bit installed, and as seen in the pictures I could obtain another 2 or 3 inches if the DW660 would not hit the motor mount block. I'm sure there is a viable...

Re: How to increase Z-Axis range?

I think I got the Z-axis range up to as much as 8 inches or so. I needed at least 5".

I'm still trying to get things tuned and tested well. I will be able to post photos soon.

Re: How to increase Z-Axis range?

Has anyone had any luck increasing there z-axis range yet? I'm hoping to do it with my shapeoko 2 when i get it.. Yes, just finished my shapeoko (pretty much a shapeoko 2). All that it took was 1) a longer Z-axis makerslide and 2) a longer lead screw to fit the makerslide length. With the version 2...

Re: New Shapeoko build acting very strangely

Static electricity is the great killer of electronics, especially in winter (drier indoor air). It causes subtle defects like this, or even latent ones that show up only after hundreds of hours. I'm not saying it was static electricity in this case -- it could have been a brief short-circuit, or so...
