Mars 2 non pro spacer for Pro Z axis height - Printable on Mars 2

thingiverse

This is a very simple cut and paste remix, credit to the originator! Ive cut it down to easily fit in the Mars 2 build volume and made 2mm alignment holes for ease of assembly. The alignment pins can be made from paper clips, bailing wire, 1.75mm filament or whatever will work. Print 4x, put them together, the spacer sits around the the vat, on the body of the printer and gives extra height to the hood. As i understand it the Mars 2 and Mars 2 Pro share almost all parts, the differences being the carbon filter and advertised 10mm taller build area on the Pro. Talking to people online ive have gotten confirmation that models sliced with Lychees Mars 2 Pro profile print fine. This leaves the stated 10mm shorter Z axis on non Pro. I have asked for measurements from users over various social media platforms and gotten confirmation that the z axis extends the same height out of the body of the printer. (Thank you, you know who you are :)) Comparing product pictures it is clear that the knob on the build plate attachment screw on the non Pro is taller, leading to it hitting the cover at full height. See the pic showing a comparison of the z setting between the variations of the mars 2. Changing the value on the nonpro to the value of the pro will enable printing to full pro height, there may even be a little bit of extra space to get even more z height but that you will have to measure for yourself :) This setting is M8026 in the config file on the included USB or in the downloadable USB files archive. The default value for the non pro is 155. Changing it to 165 will give pro build height. Apparently this was the same back on the original Mars vs Pro, with a mod it would print as tall. Here is a vid by dbholmes52 showing a different variation of the z height mod done on an original mars using a bolt and a new printed knob, the vid also goes over changing the settings required and its the same between the mars and mars 2 variants. The modded knob is obviously cleaner but not having to get to a hardware store can be a bonus for some :) https://www.youtube.com/watch?v=zZPJFCgJbwg
