I've never used retraction with Cura before so I have no experience with it, but it seems to be working on this Netfab update. Before the head jumps the drive gear quickly jumps back about half a revolution then as quickly advances and continues printing. I'm a little concerned with using retraction as I've already experienced a few plugs with my printer even without using it but so far so good. I had to adjust the M92 E value because I've got one of the first batch Ultimakers with the V1 drive bolt still... I also went into the GCode Header and removed all of the junk that causes the lines to print on the right side - and also now causes the print to start off on the right side as opposed to where I placed it. I haven't used Netfab in a long time because I've had nothing but problems recently (it used to work better on the first version). But so far so good on this update! Dave

I've got one of the first available Ultimakers from last year so maybe the belts have changed since then, but mine appear to be marked 100MXL and 300MXL. Looking at your link, the 100MXL is 8.00" and the 300MXL is 24.00". MXL is the tooth style .25" is the width (or 6.4mm if you choose) 240 is the number of teeth which will give you a 19.2" pitch length 80 is the number of teeth which will give you a 6.4" pitch length Both of which seem too short for my machine. What are your stock belts marked as? Dave
