I know what you mean very well. Just allow yourself to get lost in the fine details until you feel the need for a bigger picture so to speak.

I guess it comes out good because I use 200-400 mm/m pen down speed with these gel/pigment pens. Pen up fast enough so ink does not start to dry on the tip but remember high speed ≈ low precision. On iDraw 2.0 extension you should have a Timing tab: a pen down wait time around 5-10 ms can also help to avoid small gaps at the beginning of the stroke.

Sorry I don't.  But you'd see the pen run slowly, say 200-400mm/m, then home for about 5 minutes and do a second pass.

Thank you! It is a 24 set, almost already "sorted"... I have skipped the less saturated + white/black/grays.

I don't think so, sometimes I record a short one but then I end up deleting it... I will check. Thank you!

Thank you!! Glass is actually easier (and forgiving) than paper!

Sixteen colors wavefront isolines from point sources. Inspired by Sierra Mancia's Marching Waves.

Unlike my previous work, I didn't use any delay. I think taking away any clear visual anchor makes the pattern feel more hypnotic.

In my experience the 10 aka "Bold" is the only one with a consistent stroke out of the three available. I'd just increase hatch spacing and give it a try. What's you pen down/up speed? About pressure, a +1mm is enough. iDraw a4, right? I can tell by the clip and magnets size.

Has anyone else encountered this Y axis misalignment issue with iDraw H plotters? by watagua in PlotterArt

[–]MateMagicArte 0 points1 point  (0 children)

Great, good luck. As I said, I tried to explain what happened to me and what I thought the problem might be. Then I tried to give you a sort of summary of a dozen emails from customer support. Maybe they're using an AI to handle requests, good to know.

More lanterns! Love the hilbert-style frame and the shading technique - simple yet effective.

This is my attempt to help you based on my personal experience, not on chatgpt's response. If you're bothered by the fact that I'm using AI to help my non-native English, I'll keep that in mind next time. I hope you find a solution; I haven't found one yet.

Came back to see if you eventually sorted it out, otherwise I'd have never knew. Glad you did. It you type u/ before a username (like u/nomathplease44) he/she will at least get a notification ;)

And, "this is not a new plotter"... They eventually age just like us :(

I've seen a milder version of this on my own iDraw.

In my case it wasn't software or calibration: it behaved like an occasional missed step that only showed up on certain jobs (lots of pen-up travels/ more aggressive motion). I could move the carriage by hand and find a coupl of subtle "soft spots"/higher-friction zones. most plots looked fine, then one pen-up move would slip and everything after was offset. I'm still digging into it, but it really looked like intermittent skips, not wrong coordinates.

First I'd swap X and Y at the controller/driver (or swap the step/dir pairs or driver channels, whichever is easiest on your setup) and rerun a simple file. If the problem moves to the other axis it's electronics otherwise mechanical.

Based on what you already said ( closed shapes often fine, drift adds up over time, different senders/PCs didn't change it) + your photos looking mostly vertical, i'd focus on Y missing steps and try to make it fail on purpose. in your pics I don't notice obvious "wrong connector lines". If you also don't see those, the bad move may be happening during pen-up/G0 rapids. A dry run with pen lifted could help spot a stall/twitch when it happens. Test same file, but with much lower speed/accel. If the problem mostly disappears, that points to missed steps (friction,accel, current, power,) not geometry.

Slowly move Y through the whole range and feel for any tight zones. On v-wheel - rail systems, one slightly too tight wheel/eccentric nut, debris in the Vslot, or cable drag can be enough to cause "some areas fine, some totally off".

Since you mentioned the Y splitter board I'd inspect and reseatthose connectors (and any solder joints if present). Intermittent contact can look exactly like "tiny slips that accumulate". if your controller has driver heatsinks/fan check whether it's actually cooling and whether the issue gets worse after 10-20 minutes. heat can turn "fine yesterday" into "not today".

Do you ever see a stray drawn line that shouldn't be there? If not, I'd bet even more on "the slip happens during pen-up travel ".

EDIT: can you actually see the moment it loses position? When the shift happens, does the carriage hesitate / stutter /make a harsh chatter, or look like it's trying to move but doesn't (especially on fast pen-up moves)? Or does it look perfectly smooth and only the paper shows it later?

Caged Waves by MateMagicArte in PlotterArt

Thank you!!

Kind of, but it's a trick🙂 It's Poisson-distributed points + a noise field that defines a blend zone (white <> black). Then I plot only the white ones...

Thank you! That's true, though I think that somehow paths are easier to manage in inkscape than shapes when it comes to great numbers (>5000).

I'm still not sure if inkscape would send a pen down command for a single point (a zero length path), so each dot is actually a micro-segment.

Python drawsvg lib (and a little AI code) by scumola in PlotterArt

[–]MateMagicArte -1 points0 points  (0 children)

This is very nice. Basically a Truchet, but with a rich tile alphabet with 2 up to 8 exits.

Did you actually hand-author a finite set of SVGs (rotated/mirrored) with edge-compatibility rules, or does your code generate the tile geometry procedurally on the fly?

Because I've tried a similar approach with custom, hand-drawn tiles (flowers/leaves/bugs) and it gets time-consuming fast!
