Re: LCD Controller

My LCD controller design is fully tested, functional and robust. Let me know if you want one, parts or a PCB. All of the design information can be downloaded from the link in my original post, but note that you will need SMD soldering capabilities for construction. Note: Stepper motors make excellen...

Power Supply Cooling and Fan Replacement

If you have an original M2 power supply in the laser cut plastic case then chances are it may be running too hot due to inadequate cooling. This reduces the service life of the power supply. You can read about replacing the fan and improving the power supply cooling through appropriate vent sizing a...

Re: Spider Conversion (from 3 to 4 Point Leveling)

@mookthai

would you please correct the link in your post that is quoted from me. Somehow you have added a "gclub" at the end of my link and this is not what I posted - nor does it direct to my link.

Thanks,

LCD Controller

An LCD controller might be a useful upgrade for your M2. There is nothing worse than having your 8 hour dual colour print ruined while your computer decides that it has something more important to do such as crashing the USB communications by running your favorite anti-virus software. If you are thi...

Re: Move Z-Endstop to the bottom

There are some instructions for moving the Z stop from the top to the bottom in my Z motor upgrade write-up. I know this post is getting a wee bit old but some folk might find this and the associated firmware upgrade and leveling links useful. http://turtlesarehere.com/html/z_motor.html

Re: Spider Conversion (from 3 to 4 Point Leveling)

Here's a 'no spider machining' approach that uses those 6.2 mm diameter holes in the corners of the spider: http://turtlesarehere.com/html/4_point_leveling.html. The design approach is not original. This seems to work well and the bed is certainly more secure than with the 3 point MG system. Althoug...

Re: Why can't I reply to posts?

Looks like I can't reply to posts either. When I send stuff I get a message that the post needs to be approved, but this just doesn't seem to happen. Folk have asked some questions about my first post and I can't respond in a timely fashion. Would someone please either moderate my replies so I can b...

Re: Z Motor Upgrade

Yes, MG have seen fit to upgrade the M2 Z motor and lead screw. The reason for this appears to be captured in Brad Hill’s post at https://groups.google.com/forum/#!topic/makergear/5qC0xmOzNMQ. It concerns load, precision, accuracy, noise and motor resonance. While MG do not yet offer an upgrade kit ...

Re: Z Motor Upgrade

@willnewton. A fair call on the resolution but my primary motivation is an M2 upgrade to Revision E. One immediate advantage of the new drive is that it appears to stop the bed fall of the original drive (but I'm interested to see if this is retained as the new Z drive beds in through use). I figure...
