1. Smooth Idlers
The first thing you will do is attach the smooth idlers. Insert one of the flat head screws like this:
Next you’ll put a spacer onto the screw followed by the smooth idler and a nylock hex nut. Tighten the hex nut with moderate force.
Repeat this process with the other smooth idler.
Next you’ll be attaching the V-Wheels. There will be eight V-Wheels on the X Carriage, four of them will be attached with nylock nuts and the other four will be attached with eccentric nuts. The holes for the eccentric nuts are larger.
Start by attaching one of the top four V-Wheels with nylock nuts. You’ll insert a 25mm button head cap screw into this hole on the X Carriage.
Next slide a washer over the screw, followed by a V-Wheel and a nylock hex nut. Tighten the nut with moderate force.
Repeat that three times and your X Carriage will look like this:
Next you’ll attach the bottom V-Wheels with eccentric nuts. These nuts have a “shoulder” on them which is designed to be seated in various holes on your X-Carve.
You’ll need to adjust them later so put a V-Wheel and then a washer onto a screw and insert it into the X Carriage from the inside.
Thread the eccentric nut onto the screw making sure the “shoulder” is facing the X Carriage. Be sure to seat the shoulder in the hole on the X Carriage and tighten the screw with moderate force.
Repeat this process for the remaining three V-Wheels. When you’re done your X Carriage should look like this:
3. Positioning of Eccentric Nuts
The eccentric nuts on your X-Carve are a slick little example of good engineering. By rotating the nut you can change the position of the screw it captures. You’ll use these to adjust the position of V-Wheels all over the machine. Before going any further take a minute to position the eccentric nuts on the X Carriage to the “open” position. In this position the screw that is held by the nut is down and as far away from the top V-wheels as possible. When we refer to an eccentric nut being in the open position it will always be as far away from a static V-Wheel as possible. Here’s a photo that illustrates this concept:
This animation illustrates how the eccentric nuts change the position of the v-wheels. Keep the eccentric nuts in the “open” position for the time being, so you can easily insert the Makerslide rail in next steps. You will make the eccentric nut adjustments later on in the Calibrate section.
Note: The video shows an eccentric spacer instead of an eccentric nut, however it is the exact same concept.
4. Motor Mounting
If you purchased a stepper motor kit with your X-Carve, click on your chosen type below to mount your motors.
|NEMA 17 Stepper Motor Kit|
|25253-01||Stepper Motor NEMA 17 62 oz-in||1|
|26054-01||Aluminum GT2 Pulley 20T 5mm||1|
|25285-32||Socket Head Cap Screw M3 x 10mm||3|
|25287-10||Flat Washer M3||3|
Your NEMA 17 motor has tapped holes to accept screws, take a moment to locate them. You'll use three of the four on the motor. Orient the motor as shown with the wires pointing up and to the right:
Put a washer on each screw and insert them from the opposite side of the X Carriage using the access holes. You may find it easier to start the screws by inserting them from the side of the carriage and then tightening them through the access holes. Tighten these screws with moderate force.
|NEMA 23 Stepper Motor Kit|
|25311-04||Stepper Motor NEMA 23 140oz-in||1|
|26054-03||Aluminum GT2 Pulley 20T 1/4in||1|
|25285-41||Socket Head Cap Screw M5 x 10mm||4|
Start this step by putting a pulley on your NEMA 23 stepper motor. You will use two set screws to hold it in place. Slide it on so the edge is flush with the end of the motor shaft and tighten the screws just enough to hold it in place.
The NEMA 23 mounting holes on the X Carriage are tapped. Simply insert the screws through the motor housing and screw them into the X Carriage. Get all of the screws finger tight and then tighten them in an x-pattern with moderate force . Be sure to orient the wires of your stepper motor towards the bottom of the X Carriage.
