EZABL™ Pro – High Accuracy Auto Bed Leveling Kit

I had manually leveled my bed and been using it that way for a number of months. The problem was that the glass was warped to varying degrees and so while I could get a few areas level, other areas would not be level. As long as I printed in these distinct leveled areas, everything was good. Last week I decided to print something large, and of course, those parts in the unlevelable areas did not adhere properly. Being tired of this nonsense, I bought the EZABL Pro kit and installed it this morning. Using the printed guide and the video, the installation was easy (I had already uploaded a bootloader and new firmware). To really test how well it worked, my first print was a large item that I set to print dead center where the worst warp had been. I’m happy to report that the first layer printed perfectly – everything adhered and no curls or missing areas. I know there are lots of options out there for bed leveling, but what sets Tim’s gear apart is that he has made it easy for anyone to install and use it. It just plain works. Thanks again for a well designed and supported product.

I thought I’d order it and wait for a good day to dedicate to configuring a new setup, but overall this was far easier to setup than the Ender 3 pro and/or using an Arduino to flash the Ender firmware to Marlin ( which I was running before I bought this). A pdf scan and youtube video later and this thing is printing better than I could have imagined. On top of that, I went for the solid bed mounts which makes this all even easier.

Definitely happy with this purchase. It’s going to save me hours on printer troubleshooting and setup.

The EZABL Pro was a Christmas present to myself and at first I was not sure I was happy with it. It was a journey and in the end all of the issues were mine. That said I now have an Ender 3 Pro that is fine tuned to consistently deliver a great first layer and great quality prints overall.

The setup guide was easy to follow and detailed. I had the unit installed and configured in no time at all but initially my print quality did not change a bit. I contacted support and began my journey with Mac began. He was quick to react, provided detailed guidance and suggestions and when available include links or photos to help explain the actions he was asking me to take. We were pen pals for almost a month. This had everything to do with me and my schedule and nothing to do with TH3D/Mac. I almost always had an e-mail response within 24 hours.

In the end,all of the issue we mine and easily resolved. I now have a supremely aligned printer frame, fully grounded and calibrated sensor. Very happy with my purchase and my introduction to TH3D.

Tim – I cannot say enough about the support that Mac provided. Timely, professional, patient with a relatively new user and always there with a suggestion, advice or guidance. If all of your team provides the same level of customer service your company has a great future. Thanks for the great products and service.

Bed levelling is one of the biggest hassles of most 3D printers. I stopped 3D printing for almost a year because I was constantly getting frustrated with bed levelling issues. Now i’m back to printing everyday and I know I can just turn on the printer, fire up a print, and have consistent results every time.

Just a warning though, ABL can only compensate for so much, you have to make sure your bed is trammed reasonably well (making sure it’s as parallel as possible with the X gantry). But once you do that, you never have to touch the bed knobs ever again.

I have taken off one star because the OEM Ender 3 mount option is poorly designed, and poorly printed on top of that.
– The adapter rings to fit the 12mm sensor have elephant’s foot and therefore would not fit over the sensor’s plastic threads without damaging them
– It blocks the bolt for one of the carriage wheels
– Too thick around the screw holes, preventing the screws from threading into the carriage plate. Had to ream them with a drill bit.
– Unnecessary overhangs
– Very rough, inconsistent surface finish
The mount will get you by, but if you already have a working printer it’s much preferable to print a mount from Thingiverse. I ended up designing and printing my own mount which is much more suitable for the Mini.
