I have been collecting parts for a while now and whilst I am still waiting on some, I thought I would get started.<\/p>\n

First off I needed to cut the Makerslide<\/a> to length, the build calls for 3 x 330mm lengths and 1 x 430mm length along with 1 x 370mm length of 20x40mm profile.<\/p>\n

I cut a 330mm length off either end of a 1m length of\u00a0Makerslide<\/a>\u00a0and left the remaining piece at 340mm, this one will be used for the X axis.<\/p>\n

\"\"<\/a><\/div>\n

Next I marked out the hole positions for the hidden wiring and started to drill them out, but after the first hole started going oval and I had no hope of drilling the offset hole, I decided to use a 10mm milling cutter on my Mini Mill instead.<\/p>\n

For the 7.75mm holes, I just used an 8mm milling cutter. I tested with a spring and I believe it is still tight enough.<\/p>\n

\"\"<\/a><\/div>\n

I tried lining up the holes on the Z axis uprights against the handle piece and noticed that they did not line up! I rechecked the drawing and where I had marked and drilled and all was correct, it appears that the handle was cut with the top 2 slots 5mm up from from where they should be.<\/p>\n

Not a major issue, back to the milling machine and mill the hole up 5mm to form a slot.<\/p>\n

\"\"<\/a><\/div>\n

Since I want to mount my power supply under the Y axis,\u00a0 I decided to mill a second offset 10mm hole in the 20×40 profile that would line up with the other Z axis upright as well as continue the middle hole all the way through.<\/p>\n

I tapped two M5 threads in one end of the Y axis before attaching the foot, motor and pulley brackets.<\/p>\n

\"\"<\/a><\/div>\n

Here is a shot of the Z axis\/frame with the handle, 2 motor mounts and 2 feet attached.<\/p>\n

\"\"<\/a><\/div>\n

View from behind showing the ATmega2560<\/a>\u00a0and Ramps 1.4<\/a> board attached.<\/p>\n

\"\"<\/a><\/div>\n

I don’t have any angle brackets at present, so these will have to wait.<\/p>\n

For the X axis I have attached 2 x V wheels to each gantry plate, I am still waiting on eccentric spacers, so I can’t attach all wheels yet.<\/p>\n

I have also attached a pulley mount and the spare motor mount such that I don’t need to use 38-40mm spacers for the motor, I can use 20mm spacers instead which will be much stiffer.<\/p>\n

\"\"<\/a><\/div>\n

View from the rear of the X axis gantry.<\/p>\n

\"\"<\/a><\/div>\n

I also installed some the end stops, these are made up from 1\/4″ nylon spacers and M5 screws, although these may need to be changed for M4 grub screws if they interfere with the belts on the various axes.<\/p>\n

Here you can see the X axis gantry installed on the Z axis, some of the end stops are also visible<\/p>\n

\"\"<\/a><\/div>\n

As mentioned, I don’t have any angle brackets, so I can’t attach the Y axis at this moment in time.<\/p>\n","protected":false},"excerpt":{"rendered":"
