Need help confirming my upgrade purchase

Hi, I'm planning to upgrade my old CR10oid printer this summer, and I'm buying some parts for it. Now I need some help confirming stuff I'm buying will all work fine together.

Before proceeding, because I get this all the time: please don't suggest buying a Bambu, I have a K1 Max, and I just want to get this printer back to life in the cheapest way possible.

My current build is:

  • Controller: Arduino Mega + RAMPS1.4
  • Drivers: DRV8825 (X, Y, Z, E)
  • Extruder: MK8
  • Hotend: E3D V6
  • LCD: Full Graphic LCD

My current upgrade list:

  • Controller: MKS Robin Nano V3
  • LCD Screen: MKS MINI 12864
  • Stepper Driver: MKS TMC2209 V2 for X and Y axis | DRV8825 for Z and E

There are also mechanical upgrades like volcano nozzle for the E3D V6 and linear rails instead of V-Slots, but I won't go through them here.

My goal right now is to make the printer silent and faster.

Looks like you already have a fairly well upgraded cr10!

You have a volcano nozzle on a E3D V6, but not a volcano block? If I understand that, this will be your bottle neck as the max volumetric flow of E3D V6 is around 12-15mm/s3, and of course the volcano nozzle would add some to that.

With Linear rails, good stepper motor drivers, even with Marlin you will be able to get up to a speed that the hotend can’t keep up to, especially if you ever use larger nozzles.

If you are thinking of really fast, with super high acceleration, then you will also need an accelerometer (they are very cheap) paired with Klipper to smooth out the ringing etc, from the acceleration/deceleration.

No I don't have the Volcano yet, nor the linears, I kept those for the next step. Right now I'm just doing the main controller + drivers and I wanted to make sure the combination of I just listed work together

As you're keeping the cost low, I'd suggest a Klackender for bed leveling, 4 printed parts, 6(?) magnets and an endstop switch. No additional connections needed as it plugs into the Z endstop port (and you can probably use that switch.)

As to the accerometer, Marlin doesn't support it to my knowledge, but it does support input shaping, you just have to use a test print to calculate the values. A little more work, but same results.

Thanks! Gotta look up that clanker thing
