If you need to make cables for the CAN-FD connections and don't want to solder or crimp ZH connections, I found that JST has an alternative for the cable end. They're the ZR connector.

https://www.jst-mfg.com/product/pdf/eng/eZR.pdf

These allow you to insert all of the wires at once without having to strip the insulation. Just insert and crimp, and all of the connections are made via IDC connection.

I've not known what this connector type was called, but after googling, I found it.

Digi-Key has them in the US, I'm sure they're readily available elsewhere..

Over 100mm/sec for the entire print, even the 3mm circle. I have video of it to. Crazy to watch.

I know it's a simple print, but I've been battling crappy mechanicals, only to finally make it awesome. Was getting oval holes and bumpy round corners. Now, it's a workhorse!

@bearer I know. I've been a bit crispy. My apologies to everyone. I'll post it when I get a chance.

It's common for me to home, tram, tram, maybe tram again, then home-Z. I wanted a simple way to do it, so I started designing an electromechanical control panel. For now I just have added a handheld microswitch connected to io1 on the 6HC to accomplish all 3 of those tasks.

P.S. my switch is NC, but I have it inverted so my check value is zero instead of one.

• tap - Home All
• tap, tap-hold x 1sec - Tram
• tap, tap-hold x 2sec - Home-Z

I've been posting for quite a long time, at least years, about the same question, coming at it from different angles, trying to figure out if my problem was caused by different things each time.

What was my problem? Some call it ringing, some call it ghosting, but it didn't follow either behavior.

I was getting ripple artifacts, but they were slightly different. Sometimes it looked like the extruder was pulsing too hard, sometimes it looked like pressure advance was wrong, or I had loose belts, or too much vibration in my system. The list can go on and on.

Among other things over the years, I recently converted my Railcore to a tool changer with direct drive tools and expanded the frame to accommodate the extra hardware. This is when the print quality got really out of hand.

I basically built a new printer.

Well, the actual problem was that my XY motors were too weak. I threw on some beefier ones and my prints come out super tidy again. Can't tell the difference with prints from my Voron v0.1.

Hope that helps someone else.

It was actually really easy. Going to post a series of videos on the design and how to do it.

@gnydick NM, brain fart

@Kolbi click "Select All" check mark on list of files. Right-click, choose download.

It's not one step for all, but at least it's one step for each area.

Honestly, I feel the new version is worse in almost every way.

• There are even less buttons that can be clicked by using the space bar
• The buttons are much slower to respond, for example, clicking baby-step repeatedly is torture, you have to wait for the flash animation to finish before you can click it again
• It's clunkier, even though it looks prettier; more clicks to do the same thing
• The pop-up messages take you to the g-code console when you dismiss them

I'm being brutally honest here, this is the perfect example of form over function. I tried explaining what was needed in the RFC and warned about this kind of stuff.

The web interface should be fast, instant in response as possible given the web host, predictable, and impossible to click the wrong thing at the wrong time. It should have every single button clickable via the space bar as well as every clickable item tab-indexed.

I predicted this would be a passion project about learning a new front end library, and I was right.

Honestly, I suggest going back to square one.

Start by creating a control interfaces like this was a manufacturing machine. Oh, wait, it is!

Forget fancy menus. What do we do a lot of?

Well, when tuning and tweaking

• I want to have a g-code console and the config editor side-by-side
• give me a small mechanical control there as well
• a drop down with macros is enough, they don't need to be listed out
  • if you want to repeatedly run macros, then make a screen for that

What we don't need

• Graphs are pretty, but really, there's no reason for them to take up so much space
• The status pane is also way too big. It would work just as well as a single line along the bottom or top

I could go on and on, but I'm honestly so mad that I warned this would happen. Since updating to the latest firmware, I can't even revert to Web Control 1. Can I just re-upload it or will I have to clean up files on the SD Card?

In reality, my suggestion a long time ago was to make each of these panes a widget you can drag 'n drop and resize to make your own screens. THAT would please everyone.

As a hobbyist, I never minded slightly buggy things. It was exciting helping out projects to become better. But, I am no longer a hobbyist and use my printers professionally.

I don't want to install any more RC's just to have fixes, because almost invariably, something else is broken.

Can you please have a stable branch that is blessed and receives hot-fixes along the way? While the RC's are on a separate track for being actual Release Candidates and not things you have to install to get fixes?

This would be very beneficial to Duet customers as I'm sure they don't all want to dog-food, especially when the food is slightly spoiled 90% of the time.

As a commercial product, it just makes sense to have this release process. Frankly, it's this reason that I'm hesitant to recommend Duet products.

@o_lampe awesome, thanks. My pump is extremely quiet so that'll be nice.

@o_lampe What about a 3 phase speed controller with PWM in? Like this https://www.amazon.com/Three-Phase-Brushless-Controller-Control-Function/dp/B0F1YGJ48F

Is it possible to use such a blower for cooling?

@droftarts yes, I realized that later, let me upload it again.

@droftarts amp coin v18 - PLA.gcode

@droftarts I'm using PrusaSlicer. I'll slice up a little print and upload it.

@gnydick Any update here? This is still happening. I'm running even gentle prints with lower accel and speeds.

@Phaedrux over an hour after it hits phase 4 and has settled

@T3P3Tony 3.5.3

@T3P3Tony I think it requires an enhancement to the input shaping plugin to configure the sample time.
