Leadscrews plate and bracket for Makerfarm Pursa printer.
For this upgrade you will need to buy:
- 2pcs of 5x8mm coupler.
- 2pcs of 300mm length, 8mm diameter lead-screw with 2mm pitch and 4 starts (this was my specific choice).
- 2pcs of compatible brass nuts.

Notice that the bracket itself won't be enough because the motor centerline need do move a bit forward to mach the bracket centerline!

You will also need to make a small change (that i had drafted) at the cofiguration.h file:
#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,400,841} // (revolution/microsteps)/(pitch*starts)
You can calculate your own based on this logic.

And this is why you should do this upgrade yourself:

Of course i will be happy to assist further more.
Please upload a picture of your printing and give me feedbacks if you like.
