Using surface pen eraser function

[YuYue]

There is a function you may know if you use surface pro and surface pen to draw which is you can make your surface pen upside down (tip away from the screen and use botton on the tail draw on the screen), you can actually treat it as an eraser. This makes erase really natural.
The function works well on Paint 3D (A painting software developed by microsoft) but it doesn’t work on krita. Krita still considers the tail as pen tip and drawing instead erasering.
In fact, without this function krita can create wonderful works with surface pen as well. But I still this function can get supported, just for natural erasing.

Hello @YuYue, and welcome to the forum!

You have to assign an eraser-preset to the other end of your pen, then it will work as an eraser. If both of your pen-sides can be addressed via the driver-software of your pen. But almost all pens that ship with laptops like yours lack this fundamental piece of software and aren’t able to set up these pens properly.
The difference between Krita and other painting software is that in Krita, every brush is also an eraser, but with the settings of the brush you use. Through this specialty you can achieve erasing effects with Krita others dream off.

Edit/Add: Here I wrote in more detail about the problematic lack of the missing driver, even it is not for a Surface but for a Dell, the issue remains the same:

RE: Pop-up Palette won't appear when I right click. Is there a solution to this?

The question about the brand and model of pen and laptop was aimed at allowing us to find out something about the capabilities of this combination. Depending on the price range of your model, one of the following pens will probably have been included: “Dell Active Pen - PN5122W; Dell Premier Pen - PN7522W; Dell Premium Active Pen - PN579X”, all of which are good writing tools. Unfortunately, configuring the pens on these 2-in-1 laptops is almost always problematic, as they usually lack proper d…

Thank for your help.
But when I enable the mouse simulation, then go to krita to set shortcut, krita consider pen tip and pen tail both as mouse left click, so it’s impossible to use the way you mentioned above to solve this problem.
One thing when I using tablet tester happened and I think you should know. From the image below you may noticed that krita has correctly detected the pen tip and pen tail, just don’t support eraser function, so I think it’s a programming problem.

You can assign an eraser to the tail tip. Krita will remember anything that is assigned once, unless you manually change it again. By default it should be assigned to eraser I think.

As @raghukamath said too, you can assign an eraser-preset to that end of your pen. Just select an eraser-preset with the eraser-side of your pen.
But if I understand you correctly and if the pen software is able to set the pen in mouse and in pen-mode, then I recommend you to use it in pen-mode for painting.

Thank for all the help.
I use pen tail to select the eraser and krita do remember the pen tail as a eraser, that really helps a lot. And I found a new way to switch brushes, just make your pen upside down isn’t it?
It’s a quite new experience, I will keep working on it. Thanks once again.

Krita is awesome, I think you’ll love it and hope you’ll have much fun with Krita!
