I used a printrboard and now have a smoothieboard azteeg x5 mini. For making small changes, the smoothieboard is a lot easier. No more putting jumpers on and off, loading arduino IDE, saving a temp file, opening another program and burning the firmware. Smoothie looks to a config file that a text editor can change, then simply reset. Much easier for day to day use. I think the smoothie supporby orangezero - Delta Machines
This is all 1.75mm talk to follow.... Depending on the part, keeping in mind you can have a 0.15mm layer height with most nozzle sizes, the end product could look almost identical with a .3, .4, or .5 nozzle. Lots of factors to consider, but it is important to remember the small increase in diameter of the nozzle makes a much larger increase in area of the opening (or volume as it is extruding)by orangezero - Delta Machines
If you poke around on the shapeoko forum, you can easily get the impression that they are addictive. Lots of posts about people upgrading, wanting to make it bigger or stronger. Add a better spindle, spindle control, home switches, etc. It can be never ending just as with 3d printers. When I ask questions on the forum, I almost always get an answer in a very short amount of time. Lots of helby orangezero - CNC Routers, Mills, and Hybrid RepRapping
I've never gotten a good answer to this, but why couldn't we use a similar printed part with 3 or 4 bearings, and have them run on a standard threaded rod? Couldn't the edge of the bearing roll between two threads? (to totally eliminate slipping concerns) This seems obvious, so I'm guessing there is some reason. Is it that the pitch of most threaded rods would make for an unacceptable speed?by orangezero - Mechanics
That point is always brought up. A delta CNC is done typically for uniqueness more than anything. There r some advantages in averaging error w three towera instead of adding it up as one does in a traditional cartesion design. I'm sure someone has a better worded explanation. Another benefit would be the simplicity in the duplication of parts. I should have clarified. Mine is only going to beby orangezero - Delta Machines
I'm still fumbling with my design for a CNC delta machine. I plan to keep it very small, with a 90mm x 90mm x 50mm cutting area. I may try threaded rod with an adjacent linear smooth rod for each tower. I'm having difficulty finding any inexpensive joints. Nice metal one can be $20 a piece. I assume a cutter would simply be too much for magnets and balls. Another thought I had was to fix theby orangezero - Delta Machines
A Kossel doesn't need to have the expensive linear slides. I believed they moved to them with the Kossel pro. Many have used delrin wheels with bearings, with various extrusions. Some just have plastic carriage which fits 6 or so bearings and they slide on aluminum or steel tubing. Lots of options. Be sure to check out the magnetic joint variation as well as the cerberus and the cerberus puby orangezero - Delta Machines
Just to point out, at least a few others are doing these magnetic joints with "regular" rostock and kossel designs. I think the consensus has been that it is much more cost effective to get cylindrical magnets and use stainless steel balls (not magnetic). I'm not clear how this affects the holding power of the joint, but the N52 cylindrical magnets I just received in the mail seem pretty awesomby orangezero - Delta Machines
Just for some background, I have a printrboard with Repetier firmware using Repetier Host. I'm using a filament drive delta self-designed system (well, a healthy mix of kossel and cerberus with what I had on hand) with the end stop switches set up at the top of each rail, which I believe is typical. I'm having no luck with setting my end stops. Can someone please point me to a place that spellby orangezero - Delta Machines
