Hello to all
I have three Cartesian style 3D Printers. But now I am looking a building a CoreXY style 3D Printer. Would like information on DIY builds that would meet at least 300mm cubed, a nice good fast 3D Printer that will replace my Cartesian style 3D Printers. Was thinking of building a simple inexpensive CoreXY printer that could be upgraded to make a great 3D Printer, One that would replace all three of my Hictops.
Would like a DIY 3D Printer that could be upgraded from a simple inexpensive starter CoreXY to something that would In several inexpensive steps could equal a Voron V2.4 CoreXY
If you have a suggestion please post

Almost exactly like that.
Would like at least dual screws shown in photo below. Quad would be better as an inexpensive upgrade.
Downloaded files The PDF was DOA, "Trying to find an assembly guide. " No assembly guide was created
Installed Design Spark program measured T-Slots
2 @ 315mm 2 @ 410mm 7 @ 440mm 4 @ 510mm 7 @ 520mm
Stock Bed 220mm X 270mm Have not determined how to measure the smooth rods and led screws.
Though believe they are stock Hictop parts.
"Could not find how to print the BOM (Build of Materials)" No BOM was created for rsdoc file. Guess I will have to count parts myself.

Looking at the CoreXY Footprint it is amazing that it is smaller than my Cartesian style Hictop 3DP11/3DP12 3D Printer. Allowing for a 50% increase in print area in the same space footprint...

I was given this which will give me a head start into a CoreXY 3D Printer. It is a Scalable CoreXY V2 (HICTOP Prusa i3 hardware Converted to CoreXY). If I can get my head wrapped around what to do with this Thingiverse post. I can not find any measurements or how to assemble. Downloaded DesignSpark Mechanical 5 where I can measure the T-Slots and the Bed, though nothing else. Still this is my best shot. An the designer has no build of materials in their thingiverse post so the basic design is all I have. Oh well I have worked from less, my 1st Hictop had no assembly instructions so had to use this Youtube video in order to assembly. Most likely I will have to adjust everything to the original Hictop parts, then after getting them working can upgrade. This will be to a 300mm square build area. Though I would like to adjust design from start to have dual Z steppers and four Z smooth rods. This should make it a little nicer when it is finished. The basic parts will run about $200 then transfering my 3DP12 parts over to finish. As I have an almost complete set of spare parts this would be where all my Hictop 3DP12 parts would be appropriated from. I assume that the center T-Slot's should be framed at the height of my original Hictop about 11 1/2 inches. This would be for the length of my Lead screws and smooth rods. The single back T-Slot is only to support the extruder Motor. No ideal about the top single T-Slot, though the photos show it holding wire bundle. Wow this may be a lot easier than I first thought.

I have examined the Scalable Custom CoreXY (HICTOP Hardware converted to CoreXY).
Looking at two different versions it can be seen that this conversion can be quite simple. Parts can start from $110 and go up depending on your style for the CoreXY chosen. Actually there is a reason why I have chosen Scalable Custom CoreXY for my Hictop.
And here it is, I understood it 1st, after figuring it out I could use any CoreXY design. I still may use many other designs to suit my liking the end result will still work, an only the outward appearance will have a different personality of its own.
Some of the basic Frame Parts ordered will arrive on tuesday May 3. Should be able to quickly assembly a few versions to do some quick measurements, making sure a Creality CR10 310x310mm Aluminum Heat Bed will fit in allocated area .

I have ran into a snag.
The Scalable CoreXY V2 I have selected has a basic problem all the STL files were not created.
Missing is an important file shown in the image below.
I can not find these models or know how to remove them from the RSDOC file.
or
I am hoping someone has a similar coreXY lift part that can be adapted to this CoreXY or a complete set of plans with a complete set of STL file I could be directed to. The 2020 smooth rod holder mounts are missing an all the parts have to work in unison.

I do not think that it is it looks completely different though, if necessary could merge it with Leadscrew_holder_spacer an create my own smooth rod bearing holder. It may take several prints though sooner later would make something that would work. Parts have left Salt lake city should arrive here soon. The basic CoreXY frame should be alright, may have to improvise some of the 3D Printed model to get it together and working.
Two more views of the Part
In fact have no ideal what the model is beside the smooth rod bearing holder.
Though guarantee I will get something together and working Then I will post it here.

Not too bad learned how to use a Design Spark Mechanical Program in a few hours. Learned how to export the STL files no more problem.
May be slow but there is nothing I cannot self teach myself. I now have access to a Complete set of 3D Printed Parts

Found that Design Spark Mechanical is free and very easy to learn, though was also told that I needed to learn some CAD skills. My plate is quite full an most of my time is always used for the necessary things in life, so my 3D Printer life only seems to be operating at a lower level. I know this because I missed a sub directory, an could not find the models needed, as always going back more than once looking an found the forklift files. Have so many distractions these days completing a simple task require a lot more of my attention which this time somehow proved Murphy's Law still exists. Found the use for the other holder, is for an XT60 connector holder.
Do not like hearing my own voice videos with voice will not be done, May use captions in videos to describe while building this newest CoreXY Hictop conversion.

Frame parts arrived, could not wait I assembled the basic frame. Posting both the original and mine with changes.
I will have to fine tune this design it looks very good but will have to 3D Print a few models to see how every thing will fit together before posting any measurements. Decided on having dual Z-Axis stepper motor to eliminate the cantilever effect.

With the Covid tests stations everywhere decided to purchase all remaining parts from my Country of origin. Doing so means I have to make changes to my initial build of materials list. Will be using two MF128ZZ bearings for each of the 4 Belt idler Pulleys these are a little short of correct width an will include PLA spacer washer. My other 4 idler Belt pulleys and the Belts were found on E-Bay ordered and will be shipped from a local source. Now is the time I need to get all my presently necessary model printed, as not to waste time when the ordered parts arrive. I want to start out using an Atmega2560 I know it will work but wanted to see how far I can push it before failure set starts. An at a later time can replace the Atmega2560 with a much better 32bit controller.
Attached is my Base Marlin 2.0.9.2 Firmware.
It appear that this project is on hold waiting Parts for about 10 days. Will order the Hotbed after it is measured for the largest usable bed size.
