@oliof I like that idea, but how do I query the piezo and change the sensitivity in gcode?

undefined

@droftarts It's like the electrical noise increases once everything is homed....I did decrease the sensitivity to 340, and that helps but doesn't eliminate the issue....I'm going to try having it power down all steppers etc then retrying...

I have my Orien Piezo sensor nicely configured, BUT if I do a homing macro, it works perfectly the first time but the second one will say already triggered while homing. Looking at the Z-Probe numbers on the display, it's 524 during the first z homeing, but will jump to 545 or higher following, forcing me to do that POWER reset to get it to settle down. My question is is there a way to reset the sensor only without a full power reset? OR, why am I getting higher numbers following the first homing operation?

btw, it's a home built idex corexy

Here's my homeall.g, config.g and bed.g

I started thinking of how stall detection works, and I was wondering if it's possible to monitor the extruder stepper voltage. It seems to me that if you have a filament run out, the voltage would suddenly drop significantly as the motor force would drop. On the other end of the spectrum, a filament snag would cause the motor voltage to spike before the extruder started to grind, leading to a reduction in motor torque as the filament disappeared from under the drive gear. So, is it possible to monitor the extruder stepper voltage, and have an acceptable range? Any voltage outside of that range would trigger a problem.

@gloomyandy One other "wish list" item: a way to comment out blocks of code, rather than semi colon every single line...ie C++ uses // \ or /// / to comment out a larger block of code.

undefined

@randyl00123 I found the same confusions when trying to figure out what an 'axis' vs motor number vs drive axis, etc. I'm not new to programming, but I find it quite confusing trying to interpret what is being said. Personally, I'm finding that examples of code from other people to be more helpful when actually writing the code. The Gcode pages are ok once you actually understand what a gcode does, and it's particular switches.

Granted, I've decided to build one of the most complicated kinematics out there. I have a background that includes programming batch files back in DOS days, Qbasic, Pascal, C and C++ in College, so if I'm having a hard time understanding the nuances of the gcode explanation language, I can't even imagine the confusion of a nube.

undefined

@gloomyandy One thing I have always found confusing about the gcode explanations is the inconsistancy of definitions. For example, in M111, Pnn is the module number. What is a "module", how did it recieve a number, and what does that "number"refer to?

undefined

@chrishamm said in We need a verbose mode for general troubleshooting:

M111 P3 S1

Do I NEED to use a USB, or will the web interface not transmit the verbose? I've used M117, but wasn't aware of M111, which I'm trying at the moment. Thanks for the tip!

undefined

@phaedrux because I sometimes have gcodes run in other sub macros which have been called. For example, in my homeall.g, I call a file I've called Find_Z_Range.g. When things go ary, such as when the bed starts rising for no reason I can find, it's nice to know what command lead to it. I know from C++ coding, I would often insert line numbers or comments to help with troubleshooting. Just a way to have all macros and gcodes sent to console while running when in verbose mode. It should be able to be turned off when NOT troubleshooting.

undefined

I think it would be nice if there was a verbose mode available in console which could be enabled via an Mnnn gcode. This verbose mode would cause the duet to echo EVERY gcode before it is executed. This would be immensely helpful for troubleshooting unwanted behaviours.

undefined

@randyl00123 OK, here it is. I run G28 to home all, and I USED to have my find_Z_range macro called from the end of homeall.g, but after homeall.g, even if I manually call the macro find_Z_range.g, it doesn't move to bed center, but the bed starts rising slowly til it binds or causes other issues.

uld be. Can y

Like most things, it often takes longer to define the problem than to actually fix it. Yes, I think it would be a good idea to add more info to the M563 M669 and M584 page. Also, add how the V axis is added to the M584 command. You do need to be able to map the U and V axis to the U carriage for this kinematic to work. I finally got it to work with adding the U to the Y axis. This was after a LOT of guess work, and finally getting the X axis to work without the Y, then guessing and YAY it works....lol...When I figure out why my G30 command is giving this funky action (bed rising slowly beyond all limits with no carriage movements), I'll post it again. Thanks for all your help. I hope that I'm able to help with the overall movement toward better documentation etc. BTW, if I can be of any other assistance in writing, let me know...I know I've spent enough time with it now....lol....

@droftarts https://duet3d.dozuki.com/Wiki/ConfiguringMultipleIndependentXcarriagesCartesian

It states: A machine with 2 independent X carriages needs 4 axis motors and 2 extruder motors, total 6, which is in fact, corexyuv, but using M669 K8 causes weird problems. K5 seems to work ok...anyway, in the very next chapter on this same page, it gives
M584 X0 Y1 Z2 U3 E4:5, which is only ONE motor for the U carriage.

The required M584 for 2 independant x carriages in separate corexy configuration is:
M584 X8 Y7 Z2:5:6 U9 V0 E3:4 P4 (list four axis motors and two extruder motors = 6) XY for X carriage, and UV for U carriage.

The corexy setup page is pretty confusing as well. M669 gcode explanation page is also confusing. It states this is the matrix, without explaining what the numbers in the matrix mean. Maybe I like to do things the hard way, but I've got a college background in programming C++, and have been building i3 style printers for about five years. I wanted a challenge.....lol....found it. This is the kinematics of my new machine.

When people ask me what I make with my 3d printer, I usually say I make more 3d printers...lol...the technology is what interests me the most. Anyway, I FINALLY have things working mostly, but ONE more issue maybe you can help with. If a tool has been activated, G28 will refuse to run saying that
Warning: the height map was loaded when the current Z=0 datum was not determined probing. This may result in a height offset. sometimes when I run G30 (using a capacitive distance sensor) it refuses to run, but the bed slowly rises until it runs out of travel...ah well, one problem at a time eh? LOL

@deckingman said in Corexyuv vs corexy idex:

sing M58

The corexy and idex instructional pages truly suck. The instructions for configuring corexyuv states four motors, then go on to give M563 instructions for a different layout (corexyu). They say matrix without defining what the matrix IS. Anyway, after weeks of frustration, I FINALLY guessed and it worked. Here's the solution I came up with that WORKS for Corexyuv (Two independant corexy carriages on one X gantry using a Duet2 wifi and a duex5...
