This version is design for the following Misumi leadscrew and resin nut.

Leadscrew: MTSTRA10-300-S20-Q6
Leadscrew Nut: MTSRN10

The stainless steel leadscrew and resin nut makes for a lub free configuration. Pairing them with the Misumi LMUW-MX10 self lubricating linear bearing makes for a lubrication free setup.

You can also use either a LM10LUU or 2 LM10UU with these x-ends. I opt for the Misumi LMUW-MX10 because I want to make my printer as maintenance free as possible.

Hi tommyc, can you tell me the step per unit you use in your FW for the Z axis with this Leadscrew please :)

Ok, I have 1601.49780213 , For me it's correct.

Can you upload the scad file for the motor end. I want to change to fit the 10mm rods I have. I had these made these for my build and saw that they are for 8mm rods.

Where did you get the resin nut?


You list "Leadscrew: MTSTRA10-300-S20-Q6" as the lead screw, however Misumi seems to not like the second "T" should it be Leadscrew: MTSRA10-300-S20-Q6" ?

MTSTRA10 is stainless steel which is more suitable for lube free operation with the resin nut. MTSRA is just normal steel.

Makes sense :)

what x carriage are you using?

would I be able to use Terawatt industries leadscrew and brass nut with these x ends?  what would I need to change in the scad file?

My guess would be that they are just reselling misumi 8mm leadscrew/nut, so try this one http://www.thingiverse.com/thing:24574http://www.thingiverse.com/thi...

just wanted to know: how do you order from misumi (because i'd like to order the same screws and nuts you use) but they ask for a VAT number saying it's only for professionals..
Thank you very much,

I am not an expert in their european operations, but even in Hong Kong, they seem to be B2B only.  May be you can ask around #mendelmax on freenode to find out how people order in Europe.

 Hi, thank you very much for your reply. Could you give me the parameters you choose on their website for the screws so i can be sure to order the good ones?
thank you,

I mucked about with the SCAD file and it only spit out the idler side. Am I missing some obvious step to get the motor side?

Nevermind, I'm just terrible at openscad.

how would i change this to use 8 mm leadscrews and MTSNR8 flanged nuts from misumi?

Replace the values in the scad file with these ones, please tell me if they works for you.

leadscrew_dia_misumi = 8;

leadscrew_nut_wrench_size_misumi = 15+0.35; //D

leadscrew_nut_height_misumi = 20; //L1

leadscrew_nut_flange_size_misumi = 30+0.35; //D1

leadscrew_nut_flange_height_misumi = 5; //T

leadscrew_nut_flange_screw_pcd_misumi = 22; //P.C.D

Where did you get the orange filament? and is it ABS or PLA

Now THAT looks professional. Great work! Gonna be building a MendelMax in a month or so and this is surely going to justify stripping my Prusa for parts.. Can't Wait!

tommyc - in reply to JerZ

I did exactly that, haven't look back since.
