A three legged stool can not rock, no matter how bad the surface it's sitting on. It is perfectly stable.

Otoh, a 4 legged stool must have perfect length legs on a perfectly flat surface to avoid rocking unless the stool flexes considerably.

I have no issues on desktop, and can easily read most forums on the phone. This is the one that has forced me to use the desktop mode on my phone.

@dc42 said in Backlash compensation:

• When reversing direction in a print, if you don't take up the backlash very quickly enough then the head will be stationary for a short while, leading to over-extrusion at that point. But if you take it up too quickly then the motors will be noisy and you risk skipped steps.

Isn't the whole point of backlash compensation to reduce the mechanical dwell at a turning point? It's already sitting still in a mechanical dwell and overextruding, waiting for the axis slack to get taken up at a slow speed... Right? So, anything is better than nothing. In theory, anyway.

Sometimes it's all about those microns that nobody else cares about that sets you apart, or makes your job easier.

I find the mobile site nearly impossible to use...I have to show the desktop version, and it's substandard on a phone.

I'm using Brave browser, based on Chrome, Android 10.

When I scroll down a Topic page, before I get to the bottom, (based on scrollbar location) before I even have a chance to read all of the thread titles that ARE on the screen, a new page is loaded, and the display jumps to the bottom of the new page. The new page is close to the same location of the previous one, nearly at the bottom. That means the previous view (of yet-to-be-read threads are hidden at the top of the page. To read them, I must pull the screen down (carefully) until the previous bottom thread is visible. If I go too fast or too far, the opposite happens, where the threads is like to read are below the current display.

Am I the only one experiencing this?

Difficult to take pictures ...

The prints are small 25X9 mm. They are printed with black PLA and to complete all my camera is not very good!

Sorry for the quality of the photos !

I will do my best !

Just FYI, to get a decent photo of small black items, place them on a black background, and use lots of light.

@T3P3Tony Thanks, that worked.

I also added the M302, because I like redudancy.

Sure appreciate it!

@T3P3Tony, thanks, I posted it here:

I am setting up a system without heaters. When I try to move an E axis, I get an error "Warning: Tool 1 was not driven because its heater temperatures were not high enough or it has a heater fault". How do I disable this?

Thanks in advance!

This is my config:

T0						; select first hot end

@T3P3Tony said in How to skip homing?:

@tenaja create a tool, with just the driver, no heaters or fans. and then have T0 at the end of your config.g so its selected by default.

That let me select the tool, but then it is giving me a Temperature Reading Fault. (I have no heaters--how do I ensure that is not an issue?)

Thanks again!

How do I use an E axis without "selecting a tool"? I just want to use it to spin a spindle.

Thanks!
