Re: Chomdh's ShapeOKO2 #3702

Haven't gotten around to all my planned upgrades yet, wanted to make some v-carvings I'd promised to get done first. Today I removed the spoil boards, marked, drilled, and installed pronged T nuts. Until now I've just used double sided tape to hold my work pieces so it will be nice to have another w...

Re: First 3D printer

I'm also considering my 1st 3D printer. One thought I have is to upgrade my shapeoko2 to a 1000mm x 1000mm shapeoko3 and then use my leftover shapeoko2 rails and extra nema17s for a shapeoko based 3D printer. Can anyone offer comments as to whether or not this is a good idea? If a mechanical only SO...

Re: Bought a Dust Deputy

On the same topic, I just watched this video earlier today: http://www.iliketomakestuff.com/dust-collection/ Dust deputy is now on my list of future upgrades. Are you using a reducer to run a smaller diameter hose to your Shapeoko? Can you post pics or describe your method for attaching to the spind...

Re: How do you do tool changes?

I haven't installed home switches yet but have run a couple of 2 tool jobs now. I set $7=255 to command the motors to hold their position. I am using GRBL 0.8. Not sure if $7 has the same definition in 0.9 but I'm thinking it doesn't. This works pretty well for keeping the spindle in place while cha...

Re: Please school me in MakerCAM tabs before I waste...

Correct, makercam does not account for cutter diameter in the tab width.
So I was using a 1/8" cutter tonight to make some hold-downs and did design in some tabs. I entered 0.25 inch tab width and 0.125 inch tab height. Resulting tabs were 0.125" wide x 0.125" tall.

Re: Dewalt DNP611 as an option?

I'm thinking the ~20mm greater distance between the two x axis plates (that the z makerslide attaches to) and v wheels will reduce spindle rotation/twist about the x. Essentially a wider footprint for more stability there. A picture would help me explain.

Re: Dewalt DNP611 as an option?

I don't recall who suggested it but I will add a 2040 extrusion between my 2 x makerslides. The extra 20mm between the two x axis motor plates should help stabilize my z also. I do have the acme z upgrade, so I'll probably go with a z axis belt drive kit to allow more travel. Thanks for this recomme...

Re: Dewalt DNP611 as an option?

After reviewing the addition of a DNP611 in my CAD assembly, it's showing that the Z axis travel will be drastically reduced. The upper bearing plate on the Z axis will need to be trimmed so that it doesn't extend so far to eliminate interference with the top of the spindle. Is this what other 611 u...

Re: Chomdh's ShapeOKO2 #3702

Can't wait to get this new spindle mounted. I think the wood mounts turned out pretty good but I want to cut some aluminum ones eventually. It took a few tries to get the ID just right and now it fits like a glove. The ID was a tad undersized on my 1st attempt and I broke it trying to force it onto ...

Re: DeWalt DW611 CAD Model

@ Phinsil - that big yellow thing is where the cable enters the plastic housing.

@ Sam, thanks for sharing the model.
