Question #: 3627

Question: Hello, I'm wondering if you could make a larger laser cnc if someone asks for it? Something like 36" x 52". And how much would it be?

Current Solution

We are developing a 4 foot by 8 foot (48" x 96") laser with 80 watts of power. If you need a laser at 36" x 52", you could use the 4'x8' laser and just build a shorter table. We will have this machine available in the latter portion of 2015.

I would like to make a handheld remote for the USB CNC Board using a joystick instead of momentary switches. Could you suggest one that will work with your board.
The USB interface only works with momentary switches unfortunately. If you have extensive knowledge of digital electronics, you can apply a receiver that uses a microcontroller and a transmitter with another microcontroller that produces the pulsing signal with the controls that you need.

I am interested in the GreenBull 4x8 CNC machine kit you have; I also wish to get the laser attachment but I was wondering if its possible to have the laser larger than a 40w, say in the 80-150w range?
Currently our greenBull can only accommodate a 40W laser tube due to the size and current mounts on the spindle/laser hybrid assembly!

However please contact 281-815-7701 for further assistance with the greenBull machine.

Hello, My friend has purchased the Redfly and I am helping him a little with it. We are both very new to CNC. I am using fusion 360 at the moment. This can tool path and create gcode. I was wondering if Mach 3 or similar is still needed. Is there a tutorial you could point me to that explains how to get the Gcode from the PC, via Serial to the Redfly?
Fusion 360 is a program that allows you to design in a parametric 3 dimensional environment and also provides a great CAM toolset. Fusion 360 will produce the gcode with the CAM capabilities. The gcode is used to move the machine in various ways in order to mill the material; however, software is needed to interpret this gcode and cause the machine to move according to the gcode instructions. This is called control software. So Fusion is CAD/CAM, and you still need "control". Mach3 is one example of control software for milling and is highly recommended.

Install Mach3 onto the computer that will connect to the redFly(CNC electronics), then configure the Mach3 parameters for the machine (motor tuning, plug-ins, inputs/output, etc.). Home the machine, load the gcode into Mach3 and the machine will move according to the gcode.

A word of caution, since you are new to CNC machines, make sure you familiar yourself with the machine and the movements of the machine specific to how the gcode is arranged with respect to the coordinates of the machine. Try with very simple gcode until you get a very good understanding of how the machine will move.

I am converting a 12x36 lathe over to CNC, I am interested in a 2 axis kit. I would love one stepper motor to be no smaller than 1200oz. , and another at 6000z. Is this something that you could offer? I have two other cnc machines but this is my first converstion on my own.
We may be able to source those motors. Curious, the 6000 oz-in motor is pretty big. Do you mind explaining the application of the CNC machine and the structure that would require the large motor?

Additional Information:
The largest motors we can offer is 3900 oz-in without any mechanical help. 6000 oz-in can be resolved by mechanical means as an alternative.

For the XL Vertical Laser Machine I see it won't cut metal as it is only 80w. However, I noticed that you are working on 100w and 130w versions so will that be sufficient to cut through sheet metal? If so, how much longer until those are available?
Cutting metal with lasers even at 100W and 130W is difficult. The main problem is molten is a byproduct of lasing, which can severely damage the laser.

I'm new to this and was wondering if I connected something incorrectly... I followed the schematics found on this site for wiring. I purchased the heavy gantry kit with the USB power option. All my lights come on and motor shafts resist turning but, I cannot get movement from Mach3. How do I test my equipment to see if I've damaged anything?
By USB power do you mean the USB board? or do you mean that it is powered through USB but you have the parallel breakout board?

Additional Information:
I was referring to USB Board. Thanks for responding but that issue was resolve. I noticed that Mach 3 was downloaded twice. I copied and pasted RNR file to second copy of Mach 3 and motor runs properly. Should I remove one copy of Mach3 so there is only one? Seems like that could cause confusion. Thanks

I am interested in your Black Toe (24" X 48") machine, and am wondering if using two medium motors on the "X" and "Y" axis makes sense relative to power and alignment (racking). What would you recommend?
it is possible to install 2 motors on a single axis but you will require another driver and motor, but wire it directly to the same pins on your breakout board. Also the orientation of your motor since it is opposite side of the original so getting it to move accordingly to the original motor it will need to be orientated correctly. The slight shift could be the cause of the rod not being completely flat where the set screws are suppose to tighten the sprocket to the rod, so sanding it to a flatter surface might fix the shift in directions.
Currently do not have a kit or schematic available.

I'VE BUFFERED A PWM SIGNAL TO 0-10V ANALOG AND I WOULD LIKE USE THAT RUN YOUR 110V 2.2KW SPINDLE VFD. COULD YOU PLEASE DETAIL THE CORRECT WIRING VFD SETTINGS GET WORKING?
This will depend on the VFD you have to identify the correct terminal. The terminal on the VFD will be labeled AI1 typically (Analog Input #1). You will also need to make sure to complete the PWM circuit using the GND terminal on the VFD.

Additional Information:
I have wired my 0-10V signal to the AI1 and GND terminals as suggested. I have also set the PD-01 and PD-02 settings to 1. Still nothing. Is there something else that I am missing?

Additional Information:
Thanks for the information. Can you let me know the model of the VFD that you have?

Additional Information:
VFD Model # YL600-2S-2K20

Additional Information:
Thanks. I will check our resources and documentation to see if there is another programming setting that needs to be changed.

Additional Information:
Does your VFD have a VI terminal?

Additional Information:
No, it does not. The terminals for this VFD are as follows (seperated by dashes "-").

10V-AI1-AO2-PLC-DI5-DI3-DI1-COM
AI2-GND-AO1-DI6-DI4-DI2-FM-24V

Additional Information:
Do you have a PD070 parameter?

PD070 is the main Analog Input parameter.

The options for that parameter is:
0: 0-10V
1: 0-5V
2: 0-20mA
3: 4-20mA
4: 0-10V (4-20mA Stacked)
5: XIA
6: (VI+XIA)/2
7: (3VA+XIA)/4
8: (XIA_XIB)/2
9: Max (XIA, XIB)
10: Min (XIA, XIB)

Additional Information:
There is a PD-00 thru PD-09. PD-07 is currently set to 0.

Additional Information:
It appears that the manual I’m using “Titled YL600” is not the same as your unit. I will check our manuals and find the one that has only PD-00 to PD-09.

Additional Information:
For that VFD, the parameters are P0. The 0 may look like a D on the display.

How feasible would a vacuum hold-down system be for a vertical CNC like the greenLean?
Building a vacuum table, for any CNC machine is possible but doing it right might take a adequate amount of information and extensive planning. Depending on the overall complexity you want to build.
Example, you want sections, and valves that can be operated to close sections of the table to allow vacuum to a specific spot of you material.
It is possible and would be a very precise method to hold down your material.

Additional Information:
Thanks. It may be something I'd like to try on my greenLean at some point. Dan Spangler wrote a nice article on building a "Universal" CNC vacuum table in the latest issue of Make magazine, volume 41.
