Actually its not that slow as I'm running acme lead screws and the big NEMA34s do make even heavy things move quite fast. Currently playing around with a hybrid 4/5 axis design...by _Adrian_ - Controllers
Hey guys... I've decided to start building a rather large CNC Mill a little while back... Pulled the trigger and got most of the extruded aluminum frame, as well as some 1.5" plate that I had a friend make me a nice T-Slot work surface. Work area is a bit overkill... X = 40" Y = 20" Z = 18" Definitely not featherweight that's for sure !!! To keep everything in check and movement fluid i sprunby _Adrian_ - Controllers
Hey guys... Trying to compile the firmware for my due and install it so i can start testing the electronics pieces and make sure everything is working. So... I run through the configurator and build a custom firmware on Repetier's web page download the custom firmware, open it in IDE and then i get this beautiful string of nonsense : QuoteArduino: 1.5.5-r2 (Windows 7), Board: "Arduino Due (Progrby _Adrian_ - Repetier
Quotebobc Be aware that Rev 1A of RAMPS-FD has some undesirable issues, but is still usable (and surprisingly cheap). Rev 2a is nearing finalisation, but I can't guarantee it will go into production, although hopefully some Chinese manufacturer will pick it up. How do you tell the revisions apart ?? ( Besides markings ) Also whats the compatibility with the LCD kit from the RAMPS 1.4 ?by _Adrian_ - Extruded Aluminum Frames

QuoteTired2 Nice find, my junk boxes are not that well stocked. Well i bought them in the spring and we moved into the new place earlier this past summer. After the move i notice that a few things were missing so i just wrote them off as they were given away with some of the kids stuff that they grew out of. At least i found them, but makes me wonder what else is there that I overlooked and theby _Adrian_ - Extruded Aluminum Frames

Actually they were pretty cheap on ebay, but they sold out quick ! I was going to program them via the serial interface for the software to double check input commands VS output ( so it doesn't miss a step )by _Adrian_ - Extruded Aluminum Frames
Im using to what I originally thought was a standard NEMA23 but got Applied Motion STM23Q-3AE which have the drivers and encoder built in All i need to do is feed the power to the motor along with Step +/- and Dir +/- and everything else is going to be fed directly from the RAMPS-FD Board. For firmware I still have to see if which one is compatible with the Dueby _Adrian_ - Extruded Aluminum Frames
Not a bad design, but not uporting the bottom of the screws can lead to some issues... The main issue with people building gantry style units is the lack of strenth and stability. of your looking to meve the gantry around you need to have it braced well enough that it wont vibrate / shift while when the head is being swung about. My design has a wide footrint at the base the spread the load andby _Adrian_ - Extruded Aluminum Frames

QuoteBill Clark interesting project Adrian. Thinking about making my own 3d printer/router too. I have the big machining centers (Haas/Milltronics) to make all the nice parts but have yet to settle on the configuration. Have you seen this one ?

What do you guys think of this head ?? Dual Micron E.M.E All Metal Print Headby _Adrian_ - Extruded Aluminum Frames
Well gents, The ball screws I have are made in England by a machine shop that specializing in Mini DIY CNC components. They are 20mm diameter and 1400mm ( 1200mm threaded area ) and hardened. Came with 2 bearing blocks ( 1 fixed and 1 floated ), Zero Lash Ball Nut. The moving the table is more work as the frame has to be longer in order to be able to use the full area.

Quotemanton You may want to rethink using a gantry style design for a 3D printer. Ideally, you want the printer to move fast, so that means keeping the moving mass as low as possible, particularly in X and Y. I would think that moving the entire X and Z axis in a gantry would really slow things down. That's where the torque from the bigger motors come in... most use standard NEMA17 motors whicby _Adrian_ - Extruded Aluminum Frames
Ahh... you can always try PCB Express, but then again... Tons of support from china to make a buck LOL Anyway, I have some older SCSI U320 10' Cables kicking around that I can use for the umbilical and on the printer end I can use some of the TE connectors ( If not time to go scour the site for Smaples / Freebies ) Now a quick question about end stops... Do you guys use one for each end or jusby _Adrian_ - Extruded Aluminum Frames
A bit more progress on the drawing... I think I will have to use lead screws for the X axis though as it will have to hold the weight of the extruding/print head otherwise it will drop when you turn it off. Not a good idea when the kids will play with it... Guaranteed that something will be broken ! How warm does the work top have to be ??by _Adrian_ - Extruded Aluminum Frames
Quotebobc 1. Yes, I think they should work ok. You would just step, dir and enable to the RAMPS. 2. A heated bed is not essential for PLA, although for large parts it can help prevent warping. For ABS it is pretty much a must. 3. 1.75 mm filament allows smaller lighter extruder, but if you are using lead screw you may not be able to exploit that. The hotends are usually compatible between extruby _Adrian_ - Extruded Aluminum Frames

Hey guys... I figured I'd start a "little" project with my kids as we started a CNC Mill build that slowly got pushed to the side. It was supposed to be a gantry ( Cartesian) style mill 1000mm x 750mm 600mm ( L x W x H ) which is quite a fair sized mill for "home" use! Now they were wondering if we could still build something as a family project of course. Seen my buddy pose a few pictures of thby _Adrian_ - Extruded Aluminum Frames
Hey guys... Me and the kids are wanting to build our first 3D printer, however i was originally going to build a DIY CNC so I have some stuff left over from that. I already have quite a bit of stuff that accumulated towards a DIY CNC Mill so might as well put it to use! I have 4x Applied Motion STM23Q-3AE Yes I know...
