  • No worries. The instructions as they are get you far enough that the rest is pretty obvious. Most of my troubles were due to a lack of attention to detail on my part.

  • I followed the instructions on the firmware page to flash the firmware to my mini-Rambo. The instructions were good but I had to add one additional step which was to install the USB driver for the mini-Rambo (Windows). Without the driver the mini-Rambo was not showing up in the Ports menu of the Arduino application. There is a link to the driver…[Read more]

  • It is hard-coded in the Marlin firmware to disable all steppers after a program completes when running from the SD card. This is not desirable for the Lowrider because the gantry (and spinning router) crashes down on the table. To prevent this flash the firmware after making the following change in Configuration_adv.h:

    Replace:
    #define…[Read more]

  • When I measure the distance from the top of table to the bottom of the rail on my Lowrider there is a difference of about 1/16 inch between the two ends. This is probably due to some minor variance in the XZ or Y plates. Before I turn my Lowrider on I manually raise the gantry a bit and place some equal height blocks under the rails on both ends.…[Read more]

  • It is possible to assemble and mount the XZ Assembly upside down. I had one right side up and the other upside down. I got it completely assembled and did some pen testing before I realized my mistake. The only problem that I noticed was one side of the gantry was 1/4 inch higher than the other when it was fully lowered. This was probably my most…[Read more]

  • Bolt direction matters. Pay attention to the assembly diagrams and follow them. In particular, if you put the nut side out on the roller bearings that go through the cut outs on the Y Plate the nut will collide with the spacer. In addition the bolts for the Y Rollers on the 611 plate should have nut side facing the center of the plate. This will…[Read more]

  • Leave the bolt for the center bearing on the rollers loose until the roller gets mounted on its plate. Tightening will cause the holes on the roller to not line up with the matching holes on the plate. If you wait until after the assembly is mounted on the rails to tighten the center bolts it will be easier to get the rollers on the rails. Though,…[Read more]

  • I am mostly finished with my Lowrider build. It is up and running on a temporary table, and I have run some tests with a pen. First cuts on foam will probably be tomorrow. While it is still fresh on my mind I thought I would share some lessons learned for the benefit of future builders. Most of these come from mistakes that I made or things that…[Read more]

  • Email sent. Thanks!

  • I have been wanting to build a CNC router for a while and finally settled on the Low Rider. Can the plates be cut manually or are the tolerances tight enough that they need to be CNC’d? I don’t see an option in the store to purchase pre-cut plates. Can you suggest some places where I can get them fabricated?
