Here are two pictures of the machine I have been testing a new front/back plate configuration on.
After getting the initial batch in for prototyping, I decided to make a design change from the 3 horizontally slotted holes, to a single slotted hole.
If you are running the belt in an alternative configuration (along the makerslide), you can use the bottom slit to feed your belt through. Then pull the belt up and clamp it down between the plate and your existing belt anchor. A cool new feature is the bolt above that slot can then be used to tension the belt!
If you are running your belt in the traditional method, just run it over the top of the plate, and bolt it into plate with your existing belt anchor. Now the plates look like this:
The plates give the following benefits:
- 3/16" A36 steel (very stiff! Probably overkill.)
- Expand x-axis easily
- Opens up the front and back of your machine. Allowing larger stock to be accepted.
- gives some vertical adjustment to makerslide via slotted holes
In 2 weeks I'll have 100 sets of these X-axis uprights for sale. The price will be $25 and includes shipping for anyone domestic. If you are international and want to buy a set, you'll need to add $10 to that. I'll post a link in the 'for sale' section once the parts arrive. The sets include just the 4 brackets. You will need to source your cross pieces separately.
Cross pieces can be had from misumi at very reasonable prices. For example, a piece of 20mmx40mm (like I used) at 500mm is only $5.
Here's the link to the 20x40mm profiles: http://us.misumi-ec.com/us/ItemDetail/10302244930.htmlAs a side note, I toyed with the idea of providing the cross pieces with the kit, but in the end decided that would defeat the purpose. These plates allow you to easily scale your x-axis to your desired width. If i provided the cross pieces then I would essentially be dictating your width.
Here is a detailed PDF and DXF file along with a STEP file for all of you 3D modelers.
