GEEETech i3 32bit Rework
I have had this printer for over 3 years now. It has seen waves of reworks already and has most of the good parts to include a genuine E3D titan aero, MKS genL mainboard, TMC2208 drivers, MKS tft32 touchscreen, MKS wifi module, 0.9 degree stepper motors everywhere but Z, a 24v power supply with matched heaters, an aluminum bed with proximity switch, and Gates fiber reinforced belts. Here is what all of that looks like assembled together.. https://imagizer.imageshack.com/v2/xq90/922/PJcI0P.jpg

This printer is limited to a 200mm cube and so I want to chase precision. Making small things accurately. And the only parts I think I am going to add here are a SKR 1.4 Turbo mainboard and 4 or 5 LV8729 stepper drivers all run at 1/128 micro stepping. Past that I want to move all wires to the backside of the frame and design and print some pieces to reinforce or brace the smooth rods. So far I have this piece designed that I will print and mirror and print and install under the Z stepper motors to add support to the threaded rods under the smooth rods for Y. This will keep the top of the frame from flexing forward or the front of Y from shifting to either side. I have designed this part to be a tight fit on the threaded rods..

I have decided I want to print these parts in translucent blue PETG. And that spool isn't scheduled to arrive until tomorrow. So for now I will just keep designing the parts. I also wish to do a similar thing with the displays as what I did with my Black Widow rework. It would be cool to have a similar look to my printers. Get my own style going. So I am mounting the displays down low and leaned back at 45 degrees. voltage display from the buck lm2596 step down converter on the left and tft32 touchscreen on the right. I am integrating the display mount and a 20mm tall brace for the lower Z rods into the same part. I still have to produce the design for the right side. Here is my design for the left.. https://imagizer.imageshack.com/v2/xq90/924/3McjGv.png

And here my tft32 mount with lower z smooth rod support for the RH of the machine.. https://imagizer.imageshack.com/v2/xq90/924/hIOHFY.png

Here are my frame supports printed and installed. I will reprint the part on the left before this is all said and done.. https://imagizer.imageshack.com/v2/xq90/921/vEdbq3.jpg

This PETG really likes to stick to the build surface. So much so that some prints break just trying to release from the bed. maybe .1mm higher on the z offset might stop this from happening.. https://imagizer.imageshack.com/v2/xq90/924/ix9a2v.jpg

The z motor and mount needs to come off the frame for my supports to go on so I don't get the luxury of re printing that LH support piece later. So I fixed it now before it all goes together.. https://imagizer.imageshack.com/v2/xq90/922/MSZXoE.jpg

I have got the frame back together with my new display mounts.. https://imagizer.imageshack.com/v2/xq90/922/xTAVgp.jpg

So I have made some more progress on this rework. And the new mainboards are in. SKR 1.4 TURBO. 32 bit controller run off a 24v power supply with 5 LV8729 stepper drivers. Oh man I cant wait to get all this together and wired.. http://imagizer.imageshack.us/v2/xq90/924/OwB1k5.jpg http://imagizer.imageshack.us/v2/xq90/923/OtvBT8.jpg
