MK4 FIRMWARE

Use my Alignment Tool to re-install your feeder gears,

i did this it still is not shifting all the way to grab the 3rd and 4th color

Can you post a picture of the top of the 3DChameleon? It sounds like you have either the cam upside down, or the B/C parts out of order.

Have you seen Chris' video on assembly of the unit? You can find it here: https://www.youtube.com/watch?v=NUYJseo78tI

So, only the first picture shows the cam in the correct position. The other three all show it in the same position, at an angle that isn't correct. (They should only ever been in the 4 cardinal positions.)

Also, there are two odd screws in that... where did those come from and are you sure they're not too tight... that can easily cause it to not move to that other side.

Can you record a video of it going through all 4 positions?

This code came from your download from printable

ok I will take it out and try with the brand new unit I now have.

Let's make sure we're talking apples to apples here. You sent me two different files, but they both have different Tool Change GCodes in them. The one with our logo in it is most definitely modified, as it's using the GCode Generator, but isn't skipping the previous_extruder>-1 from our K1 profile, which prevents it from trying to reload the first color. The second one, with the 4 small blocks in it, looks correct. I also might add that the first one is using a button position (of 214) that is different than our stock 217 in the Tool Change, but not in the Start GCode block... so one of them is definitely incorrect.

ok not arguing or trying to start anything.

Ill make the change and see what happens

That's a very confusing description... Can you record a video of it? Can you confirm the commands you're sending it an what it's doing?

Bill

Can I send this entire unit to you and you so you can hook it up and try it for yourself instead of me trying to explain it or sending large video files?

I am going to order a brand new one and try it.

I don't think sending it to me is a good use of our time. I suspect that it's just a timing issue, and ordering a new unit won't fix that. The 3DChameleon has no internal storage that would save a configuration or anything like that where it would be in a bad state... all of its commands are based on what the button press pattern is, so if it's getting the wrong pattern, then a new unit won't fix that.

I really need to see what is happening and compare that to the gcode you're sending it to understand what the issue it and how to correct it.

I see the order you have in the system, but I don't think I should ship it yet without a proper understanding of what is happening to determine if the machine is really failing or just receiving bad data. (The old computer GIGO adage here applies perfectly, "Garbage in, garbage out.")

I am using Your Pursa profile from Printables on a Creality K1, forgive me I just looked at the start GCode and see what your talking about now. lol oops

Hmmm... If you're using our profile and our mounts, then you shouldn't have any issues with timing. What's different about your installation?

Bill

Not Sure, Standard K1 no mods at all, most current Creality Firmware, now I get 7 bumps and now when it goes to load filament i get a loud grinding noise until I unplug it. I will keep at it until I get it sorted out. MK3 firmware was printing almost perfect. :( I am going to start from scratch with Prusa and reload everything from scratch see if this works.
