Hi robinmdh, Yes putting tap over the sensor is a good idea, especially if the mouse is dedicated to the UM3. I am not too worried about the issue, and I don’t want cause undue work for the devs. Using the scroll wheel is great for me, especially when I am round the back of printer trying to feed new filament, no more struggling with the little lever, now I can casually wind the scroll wheel and feed the filament in, it grabs nicely. if a job is worth doing, then it is worth doing well!

As a follow up to testing the mouse/trackball. I have found that I make a number of unintentional scrolling of the UM3 wheel when I pick up or set down the mouse. I have found the best use is to not move the mouse to try and make changes, but to use the middle scroll wheel of the the mouse, then tap the left hand mouse button to select. Perhaps turn down the movement sensitivity or turn off the mouse movement option? This may not work for all users however. In the meantime, this simple mod has made my use of the equipment so much easier. If you would like me to comment on my use of this firmware in a different section then please let me know?

I have been testing the v4.2.90.20180112-test firmware and it is working well to control my UM3 with a wireless mouse. I am finding the sensitivity about right for me. The center wheel controls the scroll, and the center button or left hand button controls selection. This works well if you have trouble using the UM3 scroll/select wheel. Thank you for listening and implementing a good solution.

Thanks, I will be looking for it.

Good to know. I am looking forward to using my trackpad with my UM3.

I am looking forward to the results. An alternative arrangement: since many mice have a scroll wheel, assign the scroll to emulate the turning of the UM3 wheel and mouse click to emulate selection. This would avoid unintended selections caused by inadvertent left right movement of the mouse. This works well with a trackball too.

Thank you, I will give it a try.

Thank you, I am looking forward to the outcome.

With physical disabilities everyone is different. Mine is an issue of strength, dexterity, finger control and accessibility, also I have difficulty reaching things. I knew that my use of the UM3 would be a challenge for me, but I accept that. We all need to do things that challenge ourselves. I find operating the push/rotate button quite a challenge. Specifically when turning the rotate I always overshoot, and when pushing to select I frequently turn the rotate wheel slightly and inadvertently select the incorrect menu item. In itself this may not seem much, but after several iterations trying to make one selection, frustration rises. I don't have any problem reading the menu items on the screen. A different input method may work, I have a trackball (Kensington with a scroll wheel) that is easy operate, many people with disabilities use trackballs in lieu of a mouse. If I could plug my trackball into the USB and operate the menu, then it would work. I actually thought the best way to solve this, for me, would be through a screen interface such as a tablet or laptop. A menu item or widget in Cura comes to mind. This is what brought me to this topic. If this feature were implemented then the UM3 screen output would likely need to be echoed onto the remote screen. I understand that Ultimakers are used in many different environments, and such a solution would likely be an issue where one machine has many users. Since you asked, other challenges are the following. 1. Loading filament in the feeder - issue - not enough strength to operate the lever on the side of the feeder. 2. Lubricating all the parts - issue - I can't reach them. 3. Getting prints to stick to the bed - issue - I am still learning. I don't have any problem printing, and designing new things to print. Sorry this comment is so far off topic, I apologize in advance to everyone. Thank you for asking me.

Thank you for the reply @Daid! I understand the safety/security/operational requirements to be present at the machine. My need is more a physical one. I am a quadriplegic. The UM3 is 1 meter away from me but I cannot adequately operate the control (turn the dial and push select) but I can operate the interface of a screen input (tablet, smartphone, touch screen etc). In the sense that I wish to use a separate input interface, this is the type of remote control I am looking for. Perhaps I should open a new topic?

Thank you Indy31, your response is very helpful. The information you gave me is enough to get me going.

Sorry if I confused some of the responders. Just to be clear, I am interested in the "remote control" of the UM3. In other words, complete control of the UM3 through some action other than the of physical input and response through the UM3 "jog and select" wheel. Also, not through the use of a mouse, either physically connected, or remotely connected to the UM3. I control and recieve response from a number of devices already using SSH. I am looking for a little discussion and documentation as to the functions available using SSH as it relates to the UM3. Would you consider this request a separate topic? l agree, an alternate means of direct input using an enhanced "jog and select" wheel or mouse deserves some attention and should be addressed in a separate topic. Please point me to that discussion, or I can start a new one.

Not exactly what I was trying to do, but I will try it anyway. thank you David

I am interested in this topic. I am a quadriplegic and I have a UM3. I have very limited use of my fingers. Rotating and pressing the dial wheel is very difficult for me. I am very comfortable using computers however, and I can develop small utilities in a number of computer languages. Can all of the actions and required responses of the dial wheel be accessed in deleloper mode through SSH (or any other means)? Currently I am moving from my computer in Cura and my modeling programs to my UM3, I struggle with the dial using my knuckles and frequently select the wrong menu item. Any help with this will be great. If the information is available in some documentation that's all I need.

I am also having a large amount of stringing problems on my Ultimaker 3 using Cura 3.03 and Cura 3.04 that was not occurring with the last version of 2.x. I think that this may be a retraction issue. I am going back to 2.x until the dust settles.
