Hey guys and Happy New Year! I was wondering how close you were to releasing part 2 of https://youtu.be/JWACS6dMMQ0 detailing connections from a purchased redleaf system to your latest VFI as well as stop button and limit switch wiring? Cheers.

I am currently making a video right now. I will post the video in a few days.

Additional Information:
You guys rock!

Additional Information:
Don’t judge us until you see the video!! Haha.

Additional Information:
Here is the video that I promised. The video covers the main wiring of the VFD and spindle.

Yes, we can provide custom CNC travel lengths.

[127] Hey there, is there a way for a CNC customization with the following measurement: 47.75* 23.75'' *23.75

When purchasing the 1/2" 5 start lead screw, the length is based on the quantity. Specify the total length you will need and we will email you (if you don't contact us first) to determine the cut lengths.

For example, if you desire 36 inches of lead screw for the X axis and 12 inches of lead screw for the Y axis, just purchase 48 inches of lead screw and tell us you need this lead screw cut so you have two lengths at 36 inches and 12 inches.

If the outputs are not functioning as expected on the Mach3 USB controller, confirm that the port for the output is 3. This is a part of the configuration I did not show on the video I created on using the outputs for the RNRMotion controller.

Additional Information:
Thanks for your help. Under Ports & Pins>Output Signals I show Output#1 through Output#4 as Enabled. All have Port# set to 3. Pin Numbers for each Output# are same as Output# (Output#1 set to Pin Number 1, etc.).
Still no voltage showing on output 1 (of the board) when I input M3 in the Input section of the MDI tab. However if (in Spindle Setup tab) I set (in "Relay Control")M3 Output# to 3 and M4 Output# to 4 things work as expected. Is it possible to have the M3 signal show up on Output#1?
Thanks again.

BYCNC Response:
The book build was intended to be 20 inches x 40 inches. Larger machines were designed after the book build was introduced so customers would have the option to go bigger than what the book offered. Check out our larger machines on the website as the machines sizes range from 1 foot x 3 feet all the way up to 6 feet x 12+ feet.

User Response:
I'm not wanting to spend $3,000+ on a machine, I want to build one that will do a 4x8 sheet of wood. Will the plans in the book scale up?

BYCNC Response:
It is possible to scale the book build up, but the rigidity of the gantry would be questionable at that span, even if the height of the gantry structure were to be increased. The gantry design would need to be modified to become a box shape rather than a flat configuration. The kits on the site were design for those wanting a larger machine.

The eyebolts are used in the squaring of the machine. I would use a standard carpenters square and first run the end mill along the edge of the square to first make it parallel with the long axis. Then run the end mill along the other edge with the short axis and adjust the eye bolts and chain according to the angle that the machine is out of square.

Assumption 1: The "raw data" of 24 mrem on the TLD is the total dose received by the TLD during the 22 days that the TLD was deployed in your office. This means that (1) any TLD reader background signal has been properly subtracted, (2) the signal accumulating in the TLD during any transport or storage time between preparation (annealing) and deployment in your office has been properly subtracted and, (3) the signal accumulating in the TLD during any transport or storage time between removal from your office and processing (reading) has been properly subtracted.

With this assumption, the total dose rate in your office is (24 mrem)/(22 days), or 1.091 mrem per day. The reference background is given as 63 mrem per year which is (63 days)/(365.25 days per year) or 0.172 mrem per day. Thus the average net dose rate to the TLD during the 22 days was (1.091-0.172) = 0.919 mrem per day.

Assumption 2: The net dose rate of 0.919 mrem per day in your office is attributable to the accelerator or other regulated sources under the control of your institution.

Assumption 3: The office occupancy factor of 1/4 attributed in your question to NCRP Report 49 was misread from Table 4. The correct occupancy factor given in NCRP 49 for offices is 1.

Assumption 4: You take 20 business days per year off for vacation and holidays. You work in your office for the remaining 240 days per year.

Assumption 5: All of the accelerator shots occur while you are in your office.

Assumption 6: The average net dose rate of 0.919 mrem per day determined during the 22 days of measurement continues for a year.

Based on the data that you provided and my assumptions, your annual dose received in your office from the accelerator or other regulated sources at your institution is predicted to be (0.919 mrem per day) x (240 work days per year) = 220 mrem.

You'll need to twist and pull the collet while also canting it side to side until it comes free from the nut. It is not actually attached to the nut it just takes some jiggling to separate the two.

We will provide shim washers as a part of machine assemblies, but when purchasing lead screw and bearings, the shim washers must be purchased as well. Please give us a call and we can send them out.

I just ordered a 1/2" lead screw and bearings, etc. But I don't see any 1/2" shim washers for those bearings. If you have any, please toss 8 of them in the shipment and I'll gladly reimburse you.

Mounting the extruder to the whiteAnt can be done a couple of ways. One is to take the 4 mounting holes located at the lower portion of the z-axis rail support and use long screws protruding out. Take a thinner material and drill the four holes matching the locations of the 4 screws and screw on nuts to hold it in place. The other option would be to use the metal bracket and fasten to the edge of the rail support.
