Re: First Start Up?

Well, you don't want to force it to turn. If the delrin "loosens" up it might also have caused a backlash issue where you turn the rod and the delrin doesn't move until a fraction of a turn happens.

Re: First Start Up?

Short from seeing a video, I'm afraid I'm at a wall :?

Pictures might help too.

Re: First Start Up?

The z axis lead screw rod uncoupled from the stepper motor should be turnable by hand. If it doesn't turn, you have a mechanical assembly problem.

A typical cause is an off center rod in the flange bearing.

Re: Tapping aluminum plates

I'm thinking a ShapeOko 2 used as an X/Y table, the wasteboard moves the plate around. The z axis is used to control the Procunier plunge and retract. So the drill press is the Z axis, the ShapeOko moves the plate around. That might work, one 9 x 9 plate at a time, but hey, it's faster and better th...

Recommendation for aluminum cutting bits?

Hi there, I'm drilling M6 holes in aluminum 9x9 in 3/8 thick. There are 40 M6 holes, will be drilled in ShapeOko 2 A After the holes are drilled, the 9x9 plates are cut out in ShapeOko 2 B I plan on fastening the aluminum sheet (30 x 30 in) by screwing it into the wasteboard, or using t-slot clamps ...

Re: Tapping aluminum plates

Another approach is to use a stepper motor as the spindle. The tap would be attached to the spindle. This way the tpi is set by the number of rotations of the stepper motor. It would need electronics to drive the stepper motor closed coupled with the z stepper motor rotation. I could use an Arduino ...

Tapping aluminum plates

We currently tap 9x9 inch aluminum plates manually (drill press with Procunier attachment). It's very tedious as the plate has to be repositioned for each tap. There are approx 40 holes to tap. ShapeOko 2 would be ideal for this task. Has anybody converted their spindle for this? The Procunier attac...

Re: First Start Up?

The X axis sounds like loose wiring.

The slow movements might be due to grbl configuration (steps / mm ) check the assembly guide to set the right values.

Not sure about adjusting currents yet, except to confirm the trim pot is at most 1/2.

Re: First Start Up?

That's OK. It should be easy, just do it from the gshield, remove the wires from the terminal block and test for continuity there.

Each half of the terminal makes one coil. Test Black and Green, Red and Blue).
