I added a nut on there to snug it all down, and an extra M4 short screw and washer along with that holds the extruder and stepper nice and snug. You can just see this in the top of the pictures. I had just finished printing and attaching the V7 fan...

The opening goes to the back for easy access of the adaptor.This means, whenever you need to switch the servo, you do not need to disassmble the whole Z anymore. Put your CNC together, and check some things like stepper directions, and stepping. I...

http://www.thingiverse.com/thing:2071318 This project will bolt directly to a NEMA 17 stepper motor and I plan to use it on my upcoming robot arm project, where I will try to make a fully 3D Printable robot arm with minimal metal hardware, and...

I’ve already fitted a stepper motor to the rail and can control it and the camera with an ESP32 microcontroller. I’ve also designed an intuitive interface. The next job is to connect the two and debug. Everything has been concept tested, so there...

Put your CNC together, and check some things like stepper directions, and stepping. I had to change the stepping for X and Z, since the rods have a different lead compared to the original ones. As well I enables $1=255, so the servos lock as long...

I changed the position of the threaded inserts and added additional to replace the hex nuts. Modified the cable paths and tie wrap holes for easier printing, and thickened up some sections to print better. Modified how the front and rear clamp...

Obviously you have more to lose if you stick anything like a heatsink onto your steppers. Also you will lose a small (About 1 inch/2-3cm) strip that is about 1/4"/5mm in the front center due to the belt tensioning clip bumping into the blower. ...Unless...

That will free one stepper in the einsy board that can be used to control the extra X motor.Mirror and copy modeBoth hotends must be at the same Z height to use mirror or copy mode. This has to be achieved by hardware. One solution is to use Slice...

Update 24.12.2021 By popular demand (which means more than one), a recess for the X-axis stepper motor coupling has been added. (Happy New Year :)) After I didn't find a single Z-axis upgrade for the CNC3018 that really worked, I decided to make...

The ECAS connector is necessary for ERCF or other filament auto loaders in order to provide positive PTFE Bowden Tube retention,The Y endstop was relocated to the aft right gantry above the A stepper motor,The X endstop was moved to the X axis belt...

Also, remove the Y-Stepper motor. Now remove the Y belt on the left and right. To remove the y-shaft on the front and back, choose a small 3mm diameter metal stick and use a hammer to loosen the gears from the shaft. Then remove all gears and the...

Instead of running it up the mainboard hole, run the cable up the track just behind the mainbord housing the stepper motor cables. Flip the printer back on its wheels. There should be enough room between the bottom of the track and the frame to...

Remove the existing stepper cable (the one connected nearest the front of the printer) and replace with the cable from the new extruder cable Printer Configuration ================ The following steps must be performed after switching on the printer:...

... good as possible and this is how these development variants came about.</p><p>This short video shows the Keen-One EQ in GoTo. Also hear the sound, it just sounds clean :)GoTo Speed was 2,5°/s with 27:1 Stepperonline Steppers.&nbsp;Happy printing :)

I’ve removed the cover of the X axis stepper/end stop and relocated the end- stop switch. Please pay attention how far carriage goes to left to the homing position, you may not find it suitable for you unless you do the same change If your existing...

Once completely assembled and mounted, the mainboard with steppers and their coolers are nearly flush in the case. I have not yet found the perfect solution for that and I don't see where I can win 1 mm to make it fit, but I did not want to wait...

The shield fits nicely under the x-axis block and stepper motor and rests nicely on different parts of the extruder.I am glad you have found this model and I hope it protects your hands from burns in the future!Download InstructionsDownload the v5.0...

I found a long 4-wire stepper cable which already had JST connectors that I was able to re-patch into the mainboard connections neatly. Wired in series with the existing NC end-stop by replacing the ground side wire. Output pin to end-stop, Ground to...

Attach the stepper with 4 m3 x20mm bolts and you're done. Now print the appropriate mount, single or double and brackets. Now attach the extruder(s) to the printer using the mount which is affixed using 2 existing self-tappers as per photo. Use m3...

Print 2 sets in PETG as stepper motors can get hot enough to soften PLA. There are some built-in supports that need to be cut away. M3 hardware is needed to assemble the Z carriage. A second set of Z smooth rods are also needed on the backside...

The M92 command sets the numbers of steps the stepper motors will move based on movement instructions in your GCODE 4.Download, slice, and print the calibration square included with this Thing 5.Before removing the square from the bed, note that the...

So I fited the hole geometry, beefed up the mount arm and included a flat top-edge so it rests under the stepper motor and stops it from twisting. My Fan Shroud design has wider arms so it sits further away from the heater block and will...

These are screw-adjustable and maintain the correct belt path geometry while providing a strong and rigid mounting for the steppers. The detailed instructions are on the link here: https://www.thingiverse.com/thing:3584805 Update: 20.09.19. I've...

I used one standalone endstop like this on the stepper side of the mounting plate, and a loop clamp like this on the fan side of the mounting plate. Hopefully youre starting with a virgin length of belt…. leave yourself plenty of extra at this...
