2x HGR 35mm Rail : 1000m & 2 x 35mm Bearing Block, Square

Now you have got me here. Quite big, don't you think? Normally 20 size is enough.

By the way i have always wondered:what is the size router the guitar makers need? It seems you can clear that question now.

I chose that based on what I read from the product document, thought might be better take something better than to be sorry, would it cause any issues?

as router I'm no expert but I know some are using ones like dewalt and bosch colt.

Motors and driver arrived, just waiting for power supply and breakout board to test them out.

Now the big questions:
-what would be the ideal setting for the drivers? amps and microsteps?
-whats the correct wiring for the motor and driver? series/parallel/other?
-what type of connectors and cables should I use to connect motor and driver ? 18awg 8conductor? ethernet cables?? please point me to a site that sells good ones or is normal cat5/6 sufficient?

edit: sorry I kinda felt dumb asking the last question, now I understand that the 8 wires from the motor would be paired so the cable should be 4 core as stated in other posts. and I guess ethernet is ok for connection between stepper driver and breakout board?

however what would you recommend to connect the motor cable? straight up soldered into the long 4-core or connectors?

Yes, solder then cover each joint with heatshrink sleeving. Then solder a piece of wire about 200mm long, of the same thickness as the core wires, to the screenm then cover the whole area with a larger piece of heatshrink. Now you should have all the joints covered and that 200mm piece of wire coming out from under the large heatshrink sleeving and that wire is used to earth the screen.

Just for completeness I would suggest 4 core CY 1mm or 1.5mm cable as http://www.csecables.com/acatalog/CY-Cable-4-Core.html .. Clive

Just started learning solidworks, please bare with me I'm a total beginner in this thing but somehow managed to design the frame as I intended based on the parts I bought:

**Noplace** · 29-01-2015

Here is my design of the gantry side plates, the hiwin blocks are actually longer and would be mounted at both ends and not like the design below, I just couldn't find the right CAD model for the HGH35CA

the plates are 10mm thick and they would attach from the bottom outside to the ballscrews ( again sorry I couldn't find the proper CAD models, really new to this and self learning)

Guys I could really use some advise and guidance at this stage, really appreciate it.

Also if anyone is a solidworks expert, I couldn't figure out a way to mate the left and right linears, maybe it will show in the photo that they are not exactly aligned.

i mean the working area needed for guitar making ?

guitar body blanks are around 482x355x45mm so I should have plenty of space, even for the necks but I think thats more advanced

If you want to make a through neck bass or 8 string guitar without having to move the blank in between machining, the work area needs to be 1200 mm long, the 600 wide is okay.
But because the neck would need to positioned more carefully it makes sense to move the blank into a different position than the body was in, so 900 mm long would be okay.
