- Printed Z limit switch holders left and right - 10T85 limit switches and wires - Download of Marlin firmware from github - Existing Marlin configuration for your printer - Arduino IDE - Extra Stepper driver or similar...

The ramps board only needs the drivers (A4988) installed for X and make sure you set the proper current on them. You will also need an external driver (E) for the NEMA 23 stepper. The slider stepper motor connects to the X driver and the spool...

The electrical part of the build will probably be another $100.For the firmware settings with DRV8825 driver set either of these depending on whether you are using Y or Z for rotary axis$101 = 64 ;DRV8825 & 1.8-degree Nema 17 1/32 step$101 = 128...

I updated the .ino file to use the beeper.(Update):Replaced the file FrameSpacer.stl with new version that adds some clearance between the belt and this part by removing material from the 3 screw guides at the curved end.(Update):Uploaded schematic...

If you are using any other board/driver combination,you will need to edit the firmware I provided.Best I can tell, it seems that V1.1.5 comes with A4988, V4.2.7 comes with TMC2208 or TMC2225, and V4.2.2 can come with anyof the drivers listed.V4.2.7...

Do an internet search on A4988 driver current if you don't know what this is. Update: January 4, 2019: A few people have run into software errors when using the GRBL MI Extension. This extension depends on a software package called Python. Your...

You can find them here: https://www.pishop.us/product/pololu-socket-to-external-driver-conversion-board/ EDIT 10/24/2021 I updated the design to fit 10mm GT2 belts and NEMA 23 motors on the X and Y axis. You need to use stand alone stepper...

When I get tired of it I'll replace it with a 32-bit SKR likely. The ANET board uses A4988s and they are noisy, TMC2xxx drivers will fix that, but you need a different controller first. I don't think a 24v power supply can fit in this small size...

### Firmware You will note that there are a few combinations of mainboards/drivers that ender 3's can come with: ##### Motherboards: * V1.1.5 * V4.2.2 * V4.2.7 ##### Drivers: * HR4988 * A4988 * TMC2208 * TMC2225 The precompiled firmware is meant for...

Also moved on to using LV8729 drivers which IMO are very good, they are much quieter than A4988's and although they are specc'd for 1.5A max this is ample for a micro/small printer. Unlike TMC 2100's they are stable, and run cool. Update 24-04-17...
