I have a roll of 3mm filament I bought by clicking the wrong dropdown. Anyone had experience with 3mm? Any gotchas?
I have parts ordered to convert to magnetic rod ends, so it will be easier to swap out the whole end effector to change from 1.75mm to 3mm. I'll probably mount another NEMA23 for the 3mm extruder and either configure it as a second extruder or just move the stepper cable when I nee

I bought this one from Amazon, but IR doesn't work with the mirrors I use for my build surface, so I didn't spend a lot of time on it. I eventually removed the autoprobe altogether and calibrated the endstops and radius.

I use this mount to replace the hotend with a dial indicator for calibration. Lets you get as accurate as you care to be. After you get it flat, put the hotend back and use a feeler (or paper) to set Z max.

QuotecislomIf you do a "Home" - G28 after calibration, you lose your settings...
If you are doing calibration using G-code settings (M206, M665, M666), you must write the settings to EEPROM* using M500 to make them stick.
*This assumes you have #define EEPROM_SETTINGS turned on.

Quotealvinaw11I'm still curious about disabling the auto level tho if anyone can enlighten me on that.
Comment out #define ENABLE_AUTO_BED_LEVELING in configuration.h, or make sure your start G-code in Slic3r, etc. does NOT contain G29.

If you're using multiple layers of cardboard you might try a sheet of aluminum foil between them. That would reflect the heat back toward the bed and should speed up heating.

One thing - the thevisad's firmware is configured for a geared extruder. I had to #define INVERT_E0_DIR true

There are two ways to "level" the bed - from the bottom (bed springs) or from the top (adjust the endstops). I added screws to the top of the carriages and replaced the end effector with a dial indicator, then adjusted the endstops and DELTA_SMOOTH_ROD_OFFSET to achieve flat travel across the bed.
Later I installed the latest Marlin firmware and used M666 to adjust endstops and M665 to adjust th

Quotegaddcasey1any increase in bed heatup time?
I assume you mean decrease? It heats faster. It heats faster still if I use the other 3 cork tiles from the package to block air from the bed while it's heating.

I put a layer of cork under my bed. The tiles come 12x12 inches and are the same thickness as the acrylic washers used to attach the bed.

I had trouble maintaining ABS extruder temps until I added a fan shroud to keep the air off the hotend. Some day I will change to one that wraps the fins, but this does the job.

QuotetadawsonI just ordered from Robotdigg, and unless you pay extra for fast shipping, they ship *cheap* . . . I suggest you look again!
They quoted $45 shipping on a $75 order, didn't mention slower/cheaper options. I'll email back and ask.

I contacted RobotDigg about metal parts, but the shipping was almost as much as the parts. I guess I'll make do with plastic corners until Folger gets theirs back in stock.

You need the top endstops to be the same height from the bed, so the short rail would limit your build diameter. There is a step in the manual for determining the maximum X/Y position before the carriages hit the bottom of the rails. That rail will make your limit smaller.
You definitely need the bed thermistor. You can temporarily get by without the wire sleeve by using bread ties every few cm

I think my next upgrade (unless Folger gets aluminum corners back in stock first) will be magnetic rod joints. I already have 10x10mm N52 cylindrical magnets. I have ordered these steel balls for the carriages and end effector. Walmart sells carbon fiber hunting arrows for $3 each. I'll cut those for the rods and make ABS sockets to glue the magnets to the ends of the rods.
I'll probably use the

I used the acrylic mount that came from Folger, so the mounting ears are superfluous. (The rubber band goes to a clip on the wire loom to the effector)

You're probably right. I was just thinking about adding fans underneath and maybe heatsink fins on the motors.

hegdehogsmoker, before you try to launch a print job, make sure you can jog the end around with Pronterface. You can use the navigation buttons on the left, or use G code. For example:
G28 ;home everything
G1 F4000 Z10 ;lower to just above the surface
G1 F4000 X50 Y0 ; move it to the right
G1 F4000 X-50 Y0 ;move it to the left
G1 F4000 X0 Y50 ;move it to the back
G1 F4000 X0 Y-50 ;move it

Pay attention to the rails while you're printing. If they aren't running smooth the belt will skip and the head won't be where the Arduino thinks it is. WD40 to clean, gun oil or silicone to lube.

QuotethevisadWith anything blowing across the surface of the hotbed, you will not reach temp.
I bought a package of 12x12 cork tiles and cut one as an insulator under the bed. I prop the other 3 around the printer while the bed is heating to block breezes.

Yeah, if I do it I'll go with the American one. I'm working on adding an inductive proximity sensor, so I need to keep an aluminum surface. I guess I could unsolder the leads from the original bed and lay the PCB under it with silicone grease between.
