Hmmm. Perhaps 8mm is enough to take the filament out of their melt chamber - that would mean they have a pretty small melt chamber though. Or maybe Sigma have yet to discover that PLA will hydrolyse…..

You could also check out Prusa's smart towers but from what I saw at the TCT show, the (sacrificial) towers contained more filament than the objects being printed. They seemed awfully wasteful both in time and filament to me.

Cool I knew there was a newer version but the release notes didn’t contain anything interesting for me so I didn’t update yet…

Ok got the new daughter board today. At first thanks to Tony/David for the quick replacement!

Tested with two resistors on the DWF first and the readings have been reasonable.
I monitored the PT100 connections for any leak voltage when moving carriages, switching on heaters and fans to be sure there is not voltage on the heater channel by accident. No voltage could be monitored so.
Then connected both PT100 and looks good for now:

One thing to consider is if a 4 head axis IDEX type design was developed then XUVW would all be used by individual axis. A solution which used a XYZ to move the currently selected tool axis, while allowing UWV? to represent the actual drives makes sense.

Extending this logic further it could be conceivable that someone would want to build an IdeY (independent Y axis) or similar, or even have multiple Z axis for different tools in a tool changer type situation (OK I admit this is getting far fetched and I can't see how the mechanical design would work but bear with me).

With that in mind should IdeX type machines not be required to map "special" drive designations (U,V,W,?,?,?….) to the actual drives and then use XYZ only for the currently selected drives. If a tool specifies that multiple drives are mapped to X, Y or Z then this would of course not be a problem.

Ahhh ok well then I have to do two moves unfortunately…
Though it won't be possible for me to move X to min when U tool is selected because then X and U move U.
Unless I use the real min value but for convenience I wanted to have those values only at one point in the scripts when I have to change them I have to do that only once and not in every script...

A command to move an axis to one of its ends is not out there by any chance?

@dc42:

@(In)Sanity:

One thing that bugs me is I can move the carriage in a negative X position to get the probe closer to the edge of the bed, however doing so just results in 0's on the map. I find that very irritating.

Do you have a M208 S1 X-### command in config.g to tell the firmware that the carriage can move left as far as X-### ? If you don't, it will assume that X=0 is the lower limit.

M208 did solve the problem, I can now get within 10mm of the left edge which is close enough. The rest of the build plate I can hit each corner.

Thanks again,

Jeff

Oh, you could also simply define two macros that G92 in and out of the probe offset, to avoid running the tool change scripts. Edit: nevermind, I don't think relative g92 commands have been implemented yet.

Ahhhhh ok thanks… As always I read that but couldn't remember...

Hey David, maybe you should clarify the description of the G1 command regarding the S options.
There is just delta setup mentioned to move tower motors with S2. A note that this will move the real axis on an IDEX setup would be helpful…

The current behaviour is not useful. My excuse is that I don't have an IDEX machine to test on. I will fix it in version 1.17.

Oh well today it works… Strange...

Pfff my fault…
Extruder, heater, motor, drive... all a bit confusing 😉

Think i will still stick with your original ones for any future purchases. Was just interested if you had seen them.
