Re: FuseBox ~$300 CoreXY Printer - 8 years ago

I like the idea of 12mm rods. Just checking, these are the right sizes for the larger 2020 CoreXY: 2020 Extrusion lengths 4 x 445 mm (Frame, vertical) 4 x 380 mm (Frame, X Axis) 2 x 465 mm (Frame, Diagonal) 2 x 340 mm (Frame, Y Axis top) 2 x 300 mm (Frame, Y Axis bottom) 2 x 235 mm (Bed, Z Axis) 2 x 147mm (Bed ties) If so, I've got an order to place.

Re: FuseBox ~$300 CoreXY Printer - 8 years ago

Hi Ax, I'm getting ready to start building one of these. Just want to make sure I have the most current parts list before I go out to get the 2020 cut. Can you point me in the right direction. Thanks, Jeff oops, sorry, for the larger 200x200x280.

Re: Migbot Prusa i3 Unofficial Support Thread - 8 years ago

Does someone have a drawing of how to hook up an SSR-25DD relay to the heat bed and the reprap board? I'm not electrically inclined (even if I fly electric RC planes). A hand drawn picture will do. Even on a napkin. Thanks in advance, Jeff Nevermind. I found what I was looking for. Amazing what a google search can do.

Quoteuberjay Quoteuberjay Well, I'm back to a Thermal Runaway again. Thought I had that licked... per Ax's recommendation I increased the thickness of the wire from the supply to the control board. Still need to do so for the bed, but I was getting some good prints. Now this... on a tiny 10 minute job. Any ideas? I know... replace the bed wires... is it really that obvious a fix? I'm jus

Quoteuberjay QuoteAx No, just the power wires.. the thermistor wires do not carry much current at all. As for buying a $300 printer, the old adage apples. You get what you pay for. Thanks... again on the wires/confirmation. Yeah, I get the cheap printer thing. But I don't agree with vendors that sell it as a package that should work and, well, it doesn't. Also, it hits hard here as that $300

QuoteAx So, quick update, I have the Marlin 1.1 firmware for the Large bed with auto-levelling dead on now. Also for those of you with Auto Levelling, you don't need to use the springs so you can clamp the bed down tight, if you saw my earlier video, I just had it bolted off. I've now created this. Print 4, bolt your bed off and you'll find Auto levelling will work a lot better. What sensor are

I'm really surprised that no-one has built a DIY 3D printer where the table is totally stationary like my CNC router. (or if they have, I just haven't seen it). Jeff

Re: SOLVED - 8 years ago

QuoteAx Glad you got it fixed. The 4th printer is on the way now and it ain't a Migbot. Hop over to the CoreXY section and look for the Fusebox thread Interesting. I've got quite a few of the parts already so I'll be keeping an eye on this project. Now to just source 1515 or 2020 here in Canada. Jeff

Re: Migbot Prusa i3 Unofficial Support Thread - 8 years ago

Hey Ax, I've got a couple of questions. Do you have the large bed? If so, what size it it? And one last question/favor, could you measure your unit from the front cross beam (the one with the y-axis stepper attached to it) to the back cross beam. I'm curious as to the length of your machine as I'm sure I could add a longer bed to mine without changing anything but the bed (and of course all t

I couldn't find the Migbot/Electron drawings exactly. But if you google for "laser cut prusa i3 frame", you will find a lot of drawings in various formats (eps, dxf, pdf) that are very close to our units. These drawings might get you started. Jeff

Here's a picture of my (Migbot) Electron Prusa i3 with the dragchains attached. You can see the all the wires from the extruder encased in one chain and if you look closely, you will see the second dragchain under the plates for the Y axis and heater wires. A spare bit of the chain is coiled up on the bench. My whole unit is bolted down to the white melamine to prevent the unit from twisting e

I just wanted to pass on a little tip for those in North America (I don't know if this vehicle is sold elsewhere - let me know). Go to your local auto wrecking yard and find any Dodge/Chrysler/Plymouth van. In the lower track for the rear sliding doors is a wire/cable chain of the exact size we need for our printers. I yanked out two (one from each side) but you probably only need one. Cost m

Hi Ax, I'm using your firmware. Very cool. I love the screens. One problem I'm having is on my Electron i3, 1 click (when rotating the dial) equals 2 screens. It's driving me nuts. What is the setting in configuration.h to fix this. Thanks in advance, Jeff

I've got what may be a really stupid question but here goes. If you use a glass plate, does it have to be placed against the heating plate or can, (or should) there be a gap? There, I've done it. I've posted my stupid question. Jeff

Quotegwc2795 It will be easier to use the following . The Migbot extruder frame is not wide enough for the thumb depression to fit. I ordered the positive direction short and had to grind about 3/8" off for it to fit. It is very hard to depress because you have to press on the top of the tension screw - very fatiguing for the finger. Also this will not fit the holes in the bottom of the Migbot ex
