Q. Is the computer included?
A. NO, in keeping with our home hobbyist roots, the minimum software requirements to run Mach are very reasonable.
32-bit Desktop (with onboard parallel port, USB dongles will not work)
- 32-bit version of Windows 2000, Windows XP, Windows Vista, or Windows 7 Operating System (64-bit will not work)
- 1Ghz CPU
- 512MB RAM
- Non-integrated Video Card with 32MB RAM
- Basic Computer Skills (ability to copy/rename files, browse directories, etc)
Q. Why is your pricing so much lower than the competition?
A. We have an internet presents with low overhead at our physical facility. We also ship in bulk and have great contracts at the material suppliers. All add up to savings for you.
Q. What about Tormachs machines?
A. From our partners overseas: Syil vs. Tormach
Q. What is the spindle type?
A. Almost all our mills will be R8 collets, but we will have MT3 available.
Q. What is the spindle speed?
A. All machines come with a variable spindle speed controller. The standard machine runs from 80-1750 rpm. Our unique spindle upgrade increases the speed to a maximum of 3600 rpm. X2 machines come with a unique gear splitter that allows for low speeds and high speeds. (0-1100, 0-2500)
Q. Can the bearings in the spindle be changed for higher RPM?
A. Yes, there are precision bearing available through FAG and Timkin, however, once you increase the RPM speed above 3600 the lower speeds are no longer as low and the torque is reduced.
Q. G-Code Spindle Operation ?
A. There is a "undocumented" feature in our G-Coded spindle control. Here is the proper way to operate the spindle with your Mach controller. If you have noticed that in “CNC” mode that your spindle does nothing when you turn the spindle on……. In are in a safe “lock” mode. If you press the buttons on the face…. STILL NOTHING HAPPENS!!! (frustration) This feature is intended for your safety. So that you don’t accidentally trigger the spindle while you are working around it. You will, however, notice that once you press the “start” button the spindle won’t start, but the “stop” on the LCD display will disappear. You are now in “lock off” mode and ready for G-Code command. Now if you enter, say 500 rpm, in the spindle control and press spindle on…. Magic. To lock the spindle down, you simply press the stop button. This will make the “stop” on the LCD re-appear.
Q. Syil Machine Step Calculation:
A. Our stepper drivers are designed and built in-house. As far as I know, there is nothing out there like it. In the same driver, you can customize how many steps you want to a much higher degree than most drivers. Since it is unique, here are the steps you will want to input in your controller based on our stainless ball screws and computer speed:
Ball Screw Calculations
Ball Screw is Metric 5.08 TPI , Stepper per rev 200
Micro Steps 2 4 5 10 20 25 50 100
2032 4064 5080 10160 20320 25400 50800 101600 Steps per Inch
Maximum Traverse Speed at 25000 Hz

Maximum Traverse Speed at 35000 Hz

Maximum Traverse Speed at 45000 Hz
1329 664 531 266 133 106 53 27 IPM
These are the resolutions with each step setting:
(2 Steps) 0.0025"
(4 Steps) 0.00125"
(5 Steps) 0.001"
(10 Steps) 0.0005"
(20 Steps) 0.00025"
(25 Steps) 0.0002" Default setting on our machines
(50 Steps) 0.0001"
(100 Steps) 0.00005"
So, you can see, resolution can incredibly small, but at a price of upper end speed.
Q. Any addtional information on your Stepper drivers?
A. Sure, find it here CNC stepper driver
Q. How long does it take, once I place my order?
A. We try to keep all equipment in stock. We receive in large shipments about every 2 weeks. Delivery time can be as short as a few days, or as long as 30 days. Either way, you will not be charged until the unit is shipped to you.
Q. Can these units be disassembled for placing them in tight areas, such as a basement?
A. Absolutely. They are very easy to dismantle. In fact you will first be exposed to this process the first time you work on it, because all preservative oil needs to be cleaned from the machine. It takes about 1-1.5 hours to do a through job.
Q. My stepper motors get warm, even hot after sitting idle for a while. Is this normal?
A. Yes. The holding power of the stepper is caused by both coils of the motor with equal amounts of current through them. Without movement, they do not cool as well. This is normal.
