Know Rook 180?I've seen couple of points on the original rook 180 that could have been modified to get even more of the printer but later I saw the video about updating and creating MK1 version so I decided to stop as there should be a lot of changes and my mods will make no sense then.I decided to upload my models as they are (work in progress) where you can use some of the design already - read notes below.PS - this is based on the turned version.PS2 -  this is not tested but the changes are not so significant that it should have any bad impact. I wanted to start printing but noticed upcoming changes so I decided to wait.A. 225 BED IN 180 FRAMEWorking - I changed the Y gantry and X carriage to get around 225 mm of travel across the X while no need to extend the frame.- this uses 330 mm rods - if you can only get 350 mm you can make the holes go through the Y gantries and leave the rods sticking out - the printer frame is 354 mm wide so they will not stick out of the printer if you have enclosure.- Y carriages are moddified to leave more room for X carriage while still having the rods inserted deep enough to maintain rigidity.- X carriage is 45mm wide (original version is Print area front to back isn't increased as it needed some more time (moving steppers, rods, belt tensioners) and at that moment I noticed that changes for MK1 are coming.X carriage now uses two LM8LUU, is designed for E3D hotend style mount - use heatsink blower that attaches directly to the heatsink.Part cooling was not finished - the radial fan is supposet to mount on the back of the X carriage.B. Some minor changes to bottom frame only to print easier - mainly the slot holes for adjusting Z steppers.C. I was also planning to make Single Z stepper mod (with belt gear reduction) to make the build even cheaper and as someone coming from bedslinger I am happy even without Z tilt. I am just not sure - are there any other major disadvantages this would bring? The only thing I can think of is speed/acceleration as one stepper with reduction is obviously not going to compete well against 3 steppers. Thanks Rolohaun!
