ModeratorSure sounds odd.
Are you sure it’s double the material, rather than half the X,Y velocity?Is it pure linear Gcode, or have you crafted in loops or “macros”?
CoolTerm on RasPi should be ideal for this.
Have you tried making just one item to see if issues is Z related rather than duration of job?February 22, 2018 at 7:18 pm in reply to: 3d Printing with Tinyg ( rotational axis A trouble ) #10862ModeratorInteresting Project.
I see nothing obvious in your settings, but must admit we see very little rotational axis examples.What do you use as a Gcode sender?
Do you see anything in the status reports indicating an increase in the rotational velocity as the material delivery increases?
Like the others, I have to wonder about the viscosity of your material changing over a long period of time, perhaps due to the shaking?maybe the slurry separates over time, with the heavier material depositing slower, then a more liquid flow occurs during the later stages?
Perhaps try running and manually keeping the reservoir at approximately the same level of fill?ModeratorSo I am not at all clear what you are looking for.
Yes, when someone says Post Processor in this space it usually means tuning the backend of a CAM system for the target motion machine.
If you are looking for a processor that morphs 3 axis G code into 5 axis Gcode, I don’t think the Synthetos folks are focussed on that.
ModeratorPost processing is provided by the Gcode generation software, not tinyG.
Try the support interface with whatever generator you are usingModeratorGood news, I guess.
What did you determine that minimum to be?ModeratorThanks SteveD for your experienced participation.
I created a sticky reference to this thread to help future visitors
ModeratorSet parameter $p1pof=0.0 That should turn off the PWM after boot.
The default value has PWM set to 10% duty cycle when off, not sure why.The LED should flash for 10 seconds after a reset.
That is the bootloader running and waiting for you to connect with AVRDUDE, to initiate a code download.
After 10 secs the bootloader will load and run the previously installed FW.I have never played with 449.01.
It was the most recent attempt to resolve the issues of arc-end disconnect errors(problems with G2 and G3 moves).ModeratorRCG3: SteveD’s suggestion may work but is inconsistent with tinyG operation ‘conventions’.
See the note at the bottom of this reference: https://github.com/synthetos/TinyG/wiki/Homing-and-Limits-Description-and-Operation#homing-configuration-settings
If you use a Zmax switch for homing, tinyG G28.2 will home up to Z first and set Zmax = 0Again, I have no hands on experience with this, but have to wonder if you issue has its roots in the cncjs probe macro step
; Set the active WCS Z0
G10 L20 P1 Z10You were attempting to run a probe cycle after a previous probe cycle, i.e. with the WCS offset still in place.
I believe the proper workflow needs to be:1. Clear offsets
2. Home your machine
3. Run probe cycleIf you intended to use the Touchplate to find the top of your material,
you Gcode should be generated cutting into the material in the -Z direction, down from zero or down from an offset.
I’ll guess that the cncjs folks who implemented the Probe macro assume that the Gcode cuts down from 0 and use the offset to achieve move “offset zero” to the proper point.The values of $ztn and $ztm are really only called into play if you use soft limits.
If you intend to use offsets in your workflow, whether manually (user defined) or automatically (via homing and probing), you have to be mindful of that when generating and archiving Gcode files for future use.
ModeratorAre you direct wiring the TB6600 to the Due, or using buffers?
the spec sheet says 3.3V to 24V inputs, direct drive from DUE may be marginal (it is 3.3V logic)ModeratorPost a $$ dump of your parameter set to a cloud drive and provide a URL.
ModeratorPost a $$ dump of your parameter set to a cloud drive and provide a URL.
ModeratorFrankly, I’m not sure.
I have not used the function nor experimented with it.Perhaps someone with more experience will stop by.
ModeratorI am curious as to why you have $G54z=19mm.
If you set $G54z=0, do you still see the wrong direction movement?
ModeratorI don’t understand the syntax you have shown
What should “2.9385 G0 Z-1 3.460” produce?What are your Z motor and Z axis parameters?
ModeratorCan you post your parameter set to a cloud drive and provide a link?
Does homing work OK for you?
Have you tried manually entering the
G38.2 Z-10 F20
from the command line, with same results? -
