Thanks for the firmware. Once I have all of the parts printed i will be placing my order for the hardware from ya!
The hot end on my da vinci jr is struggling
Neil
Soā¦ How well does it work?
What could this be? Getting excited now. Now that I have the cnc machine moving. I need to learn how to use this estlcam software to cut out the frame.
Too dang cool man. Really digging it. I just love how simplistic it is. I have a few days off next week.Iām going to get my frame cut out during that time.keep up the nice work bud.post more build pics. Iām sure Ryan would appreciate it as well.
Neil
Looking good buddy. I finally got all my parts printed, my Mpcnc moves. I got my mill bits. Just need to cut a frame.
Neil
Iām hoping power up is this evening. 
itās going well so far with almost everything done but electricā¦ But, watching the Olympics while building isnāt a great plan and has caused some repeated dis-assembly re-assembly moments.
You should throw together a small build log to help us out in the future 
Neil
Oh man, sorry I totally forgot to make some instructions. I will hopefully be building a new one soon and will make them with that build. I know it wonāt help you now, sorry again.
Ryan,
You are like me so many projects so little time. I was going to try and help you out and post in builds and things built as I build. Iāll be putting my larger order in for everything I still need for the 3d printer this week (I have parts printed, Mpcnc about to cut its first parts). If I get it all working I took Wednesday-Friday of off work to get some things doneā¦
Neil
Hooked up and moving well. Need help on the heated bed. You print in the aluminum side, right? Not the black sideā¦
Wiring was a bit of a challenge for an hourā¦
I also have no idea how you meant to hook up the timing belt. What I have works and looks reasonable, but doesnāt quite feel perfectā¦ (Pics tomorrow)
Thatās a bit easier than I thoughtā¦ I used a zip tie on the other end too as a just in caseā¦
How do you seal the thermoster into the heated bed?
hahaha, your killing me Ryan. I went to place my order for the parts today and you are out of the mk3 bedā¦ dang itā¦ you think you will stock soon or should I look on ebay?
Neil
Oh man so sorry, Moving is so much harder when there is a business coming along for the ride! I have been trying to keep up with everything but I didnāt do so well. I have placed the order but sadly I am just paying for it now. It usually takes about a week. I do have 1 of the beds I use here, the PCB style. I put cheap hardware store glass on top 8x8. Let me know if your interested we can work out the details.
I am in no hurry at all buddy. I was just giving you a hard time. No need to work a special order in for me bud. You do enough around here as is. I will wait patiently lol. Have a great week Ryan.
Neil
Here are some notes on my build that may help:
- put bearings in all the pieces first. 1 bearing in each piece for the bed, 2 in all the rest except for the piece that holds the extruder which gets 3 (two on top, one on bottom).
- put the end stop screws and end stops onto the plastic pieces. pictures on the web site are adequate to see how that works.
- put bearings in the plastic pieces. pictures are adequate again.
- solder wires onto end stops
- assemble the frame (corners and motor blocks and gantry) - check for square
- put motor mounts and pulley for the bed on the frame.
- put the plastic piece that holds the timing chain on the bed. * make sure that it aligns with the motor and pulley pieces. *
- put the bearings on the bed.
- put the end pieces on one end of the rods for the bed.
- put the bed on the rods.
- other end pieces on those same rods.
- put on all the stepper motors
- put the bed on the frame. - check for square
- build the x axis. - this is the longest two rods into the plastic pieces and the carriage onto the rods. put the timing chain on at this point too. it will be easier. make sure the brass nuts are also put on at this point.
- put the top of the y axis rods on the frame if you didnāt already.
- put the x axis on the y axis rods. put the y axis rods into the mounts at the top of the gantry, slide them up and then down into the motor mounts at the bottom.
- slide the threaded rods down through the brass nuts and lock them into the steppers. check for square.
- bottom timing chain. - set the end stop screw lengths now. make sure that they touch at the appropriate points.
- route wires
- mount power supply and ramps
- mount extruder (and wire it if necessary)
- headed bed
- plug in wires
- power up and initial movement test. ā home it.
- wire cleanup.
for the thermistor in the bed I used a high temperature silicon gasket compound and let it dry overnight. do this in advance.
I also wired in a power switch for the whole unit. I recommend doing this as well.
since I have an MPCNC, I put two 8 pin DIN circular plugs on the extruder (one of the plugs for extruder power, the other plug for two fans and the thermistor) - this lets me move the extruder back and forth with minimal effort. I cut a wooden block and mounted the DINās into that and glued it to the frame next to where the ramps is mounted in order to facilitate easy transfer back and forth.
the mk3 bed uses #4 screws and not #6. - get one inch ones.
the wire bundle I have is pretty big. you MAY want to trim a long section of the stepper wires out if you donāt like large bundles. I donāt mind and I left them.
I recommend using shrink tube on all connections when you solder them.
I usually run mine through a raspberry pi using repetier server and if you do the same, you may need to flash the speed down to 128k baud from 250k.
still to do is print off a box to hold the display
and make a filament holder and a couple things to route it.
hope this helps.
