Touch screen poor quality?

I recently got a Palette 3 pro, and was extremely disappointed in the screen from the first time I pressed a button. The touch functions are intermittent at best, and the amount of force required to trigger them is enough to deform the LCD and cause visual artefacts on the screen, almost as if this is a non-touch rated LCD with a touch membrane over top.

In this day and age where glass faced touch LCDs are available on amazon for DIY projects at very reasonable costs, this screen feels like a bargain basement reject.

I’ve resorted to using a stylus to get accurate touch points, but constantly feel like I’m going to break the display watching the patches of LCD crystals squish around.

Answer this question I have this problem too

I too have to use a stylus.

New firmware helps, and makes the device at least usable, but does NOT completely resolve the issue. At least on my P3, there is still substantial discoloration to the image, even with extremely light touches, and certain areas of the screen seem to not respond very well.

At least this is a step in the right direction.

I hadn't thought about using a stylus, but I will try it. I just got the new firmware and it's a little better, but there is much room for continued improvement. Let's not stop here guys; we need to have this put in the list of continued improvements along the way please. The software makes this $800 unit feel very "unfinished." I realize we are at the beginning of the product cycle, but we ARE on revision #3 of the Palette. I am excited to see where you can take this product!

The issue is the touch screen. Its total crap for pressing with fingers. I have found using an allen wrench actually works VERY well and you dont need to press hard at all. Or one of the thumb screws on the P3, you will always have one out cause you will always be fixing it :)

Actually I don’t think the issue is with the touchscreen.

The software they are running is basically running a chrome browser in an embedded device and then rendering their react based ui on it.

What I am saying is that the software is lagging, not the touch screen.

Overall hardware seems pretty good on the Palette 3(pro) but the software is very very lacking. Many many features are not implemented, there are a lot of bugs. Hope they will fix this with some updates.

I disagree with this statement. The hardware of the touch screen is substantially inferior even to my Ender 5 Plus, which is a full 3D printer costing less than the Palette. I will be linking a video shortly showing the side by side comparison. It will be linked in a reply to Fatima's comment below.

The software side seems to be good, loading the web page on a regular browser by going to the ip address + :5000 gives access to a very responsive copy of the UI that has no lag whatsoever and reliably responds to all clicks.

Yes,

When you load the ui on port :5000, you are loading it on a computer which is not an embedded and slow device. Chromium was not designed to run on an embedded device, it runs very very slowly.

@serghov That sort of makes sense, but literally sitting right next to my Palette 3, I have a raspberry pi 2 running Repetier Server, with a 7 inch glass front touch-screen that is infinitely more responsive and an absolute dream to use in comparison. It is fast enough rendering to display real time graphs and switch between tabs on a moderately complex interface. I don't see how the embedded current generation pi board could be this much slower than an old rpi 2. plus the touch screen feels seriously cheap, nowhere close to the quality I would expect out of an 800 dollar device.

Hi Zeno,

I apologize for any difficulty this has been causing you, as Sergey mentioned the issue is not with the touchscreen itself. Our engineering team is currently working on an update to allow better usage of the touchscreen moving forward, you can expect that update soon. In the meantime, please continue to use your stylus as a workaround.

I very much disagree with the issue not being with the touchscreen. Here is a video showing the issues with the touch screen. I directly compare against the touchscreen on my Ender 5 Plus, a printer which costs slightly less than the Palette. https://youtu.be/cYwzjmiJuhQ

Even with very soft touches, a substantial band of the screen shows splotches and discoloration, and touch is very unresponsive all across the screen, again even when compared to a budget level 3D printer.

When loading the interface in a standard browser via ip-address:5000, it is very responsive and works reliably.

by

Is it still happening?

by

Definitely still an issue. Firmware updates helped marginally, but the screen still discolors severely when pressed and often buttons don't reply on the first few presses.
