#516 Upgrades and Build Log

Prior to using mine at all, I performed the following upgrades Dual Motor Y Drive All NEMA 23 motors (Y, X, Z) TinyG controller 24V 10A Linear power supply ACME Thread Z Axis DW660 Spindle w/ HDPE Mounts At that point, I cut a bunch of 0.5mm ABS ... extremely messy but it led me to identify 3 additi...

Re: GT2 pulley and belt

Wish I'd seen this sooner, I just got back from Suzhou yesterday ... I go to often but normally to the Shenzhen/Zhuhai area.

Re: Seattle Meetup?

I am in Seattle and avail Thu & Fri night ... I am new to the area (from Austin, TX) so don't know too many people outside of my job in Redmond. I am close to maple leaf, green lake, wallingford, which I think is north of fremont but not by much so i could drive / take the bus. Is this on?

Techniques for cutting ABS (feedrate, end mill, etc)

I've got some smallish 70mm x 25mm x 1mm ABS plates that I'd like to make some inside cuts. Basically cutting out holes for connectors and so on. I've made a spoil board that holds the part and a clamp that keeps it in place. The difficulty is the edges come out really rough. I am using some generic...

Re: Problem with tightening bearings [625z, inventables kit]

I'll just add one note: On my bearings I found that several of them had more than 1 of the plastic dust shields on them. This caused them to have much higher friction than normal when they are tightened in place. I found a couple of them during the initial inspection but missed several. After removi...

Re: shapeoko tolerances

I don't know that I've seen it posted. However, on mine the Y carriage is too flexible, so I've put together some additional components to make it stiffer. After I get done with that, I'll likely measure the system and see what I come up with. Its a good design, but I think the Y needs some help to ...

Re: Test G Code shows my Y is off (backlash)

Actually for X I'll probably use corners that fit the extrusion and just bolt those on the outside to a plate. With the small adjustment in the connectors, I should be able to square it up. Again, Y is much less stiff than I feel comfortable using, so that is where I spent my effort so far. I may be...

Re: Test G Code shows my Y is off (backlash)

I've actually taken a different approach to fix this problem. I won't say its limited to Y, but Y (at least one mine) is very flexible and therefore easy to get "out of square". You can think of it as a mass-spring system where the mass is the spindle stuck into some material. As you move further aw...
