Introduction
Introduction
In this guide, we are going to upgrade the platform on your CW1 to the removable CW1S platform with the protective FEP foil.
Note this upgrade is the platform upgrade only. Factory-built CW1S contains a revised heating system for the drying function which we won't be changing with this upgrade.
CW1S uses specific firmware because of different heat management. Stay with the CW1 firmware even after upgrading to this revised platform.
Apart from the FEP foil, you will need to print two new plastic parts, printable on any of the Original Prusa FDM printers.
If you do not have a capability of printing these parts, please try searching for someone nearby who does, via prusaprinters.org/world
Another option is buying the printed parts along with the upgrade kit (containing just the FEP foil) on Prusa E-shop.

Download the necessary files from Prusaprinters.org
There are not only STL files but also pre-slided G-codes for Original Prusa MK3S/+ and MINI/+ printers available, ready to print.
Print both the Platform Star and the Ring.

Remove the three M3x8 screws from the center of the platform. Take these aside. We will reuse these later.
Remove the platorm from the machine.
Remove the eight M3x8 screws from the ring around the platform. Remove the black printed ring and take it aside. We will use the newly printed one in the upcoming steps instead.
Save all the screws and the bare metal sheet. We will need it later.

Disassembly
Loosen the grub screw on the bottom of the metal magnetic platform by using the 2mm Allen key.
Don't remove the grub screw entirely. Just loosen it enough so the magnetic platform can be taken out.
Remove the magnetic platform off the motor shaft by sliding it up.

Insert the magnetic platform into the printed platform star.
Check that the grub screw entry in the magnetic platform is accessible through the recess in the platform star.
Fix the platform star assembly together with the three M3x8b screws by using the 2mm hex key.

Attach the platform star assembly onto the motor shaft on your CW1.
Notice the motor shaft has a flat part on one side.
The grub screw on the side of the platform star assembly must go against the flat part of the shaft.
Position both parts so the grub screw leans against the flat part of the motor shaft.

Insert the 2mm Allen key into the grub screw on its side while holding the platform star assembly with your other hand. Don't tighten it up yet.
Hold the platform star assembly with your hand so the top of the motor shaft is flush with the flat surface of the magnetic star.
Maintain the grub screw to the flat part of the shaft alignment we have adjusted earlier.
After the alignment is correct, tighten the grub screw to fix the platform star assembly in place.

For the upcoming steps, please prepare:
Protective FEP foil (1x)
Platform metal sheet (1x)
Ring (1x)
Make sure you are using the new ring which has cutouts on the bottom side, not the old ring you have removed from the CW1 earlier. The old ring is flat on both sides.
M3x8b screws (8x)

Put the platform metal sheet onto the platform ring.
One side of the printed ring is flat and has eight holes for the screws. Make sure it faces up.
One side of the metal sheet has a brushed surface and there are chamfers around the holes for the screws. Make sure it faces up too.

There are 8 ways to position the parts one to another.
Find a correct position in which:
Parts are aligned so each of the three holes in the metal plate are pointing towards the FEP foil attachment point visible from the outside of the ring.
AND all of the holes in the printed part are accessible through the openings in the platform metal sheet.
Attach the metal sheet with the 8 M3x8b screws.

Place the FEP foil on a flat surface with the cutout part facing up. There are protective layers on both sides of the FEP foil. Remove the one on top.
Put the platform onto the FEP foil. The metal part must be facing down. Adjust its position so the attachment points are pointed to the corresponding cutouts on the FEP foil and the platform is centered.
Lift the tabs on the FEP foil up and hook them up into the attachment points on the platform.
Great! The platform is ready!

Rotate the platform with your hand to verify it is able to move freely. If not, try re-attaching the platform on the platform star.
Congratulations. Your CW1 with CW1S upgraded platform is ready to roll!
Happy curing and washing!
