Yes I did Sergio. Thanks for taking the time to draw that very clear diagram. I wish I would have had it sooner because I had to do some digging to find out how to wire it.
The problem cleared itself up as I worked with it. I am not sure what happened but I am suspecting that it was a grounding problem. It is securely grounded now and reading correctly. |

Where is the information on how to set up Mach 3? Also this might be a stupid question but why is it that Shopbot software cannot control the MechMate?
|

Look at the Mach3 website for their support and videos.
The shopbot software only runs in their own controller. You can use a shopbot controller if you want to. |

Would their controller replace the breakout board? I already have my box put together with a PMDX-122 and I am planning to use Mach3. I loaded it up last night and I am endeavoring to figure it out. I had Shopbot 3 pretty much mastered. That is why I asked.

Yes, their controller replaces at least the PMDX-122, maybe more. I am not up to date with what they sell these days.

Page 4 of the PMDX-122 user manual located hereshows the options for powering the board. I have a standard 115acv to 9dcv adapter that will plug right into the coaxial jack on the breakout board. If I am understanding the manual correctly I can use that, am I right?

9VDC is fine. I have even used a 9V battery as a test.

Thanks for the quick reply! I have not been able to get my motors to turn yet... Just kind of going over the whole thing trying to troubleshoot it.

Getting the motors to turn can be very frustrating. In the Troubleshooting section you will find some help if you get stuck.

We Have LIFTOFF!!! It was the charge pump settings in mach3. Man you don't know how good that makes me feel!

Blake,
Be vary careful NOT to disconnect the Power Supply from the Gecko's "live." The problem is that the Gecko's act to discharge the capacitor. If you don't have them connected when the power supply is turned off, there is no place for the charge on the capacitor to go. Also, do not turn on the power supply while it is disconnected from the Gecko's, then turn it off and connect the Gecko's without discharging the capacitor. This is the same as putting a switch between the power supply and the Gecko's which is strictly forbidden by Geckodrive, Inc. The best thing to do is to use a "low" value (1 to 5 ohms) "high" wattage (15 to 25 watts) resistor to discharge the capacitor if the Gecko's are not connected when you turn off the power supply. Just touch leads to the resistor to the two poles of the capacitor. You will draw a small arc. You should not use a straight piece of wire or screw driver for these large capacitors. After verifying that your power supply is producing the correct voltage, you should connect it to the Gecko's and leave it connected. You should turn on and off the power supply on the AC side, not the DC side. Hope this helps. |

Congratulations...I know the feeling.

Connecting a light bulb accross the cap is another way to discharge, you will know the cap is fully discharge when the light goes off. |

Complete except for cables
All that is left is to hook up the motor cables. And install limit switches. I hope to have it operational tomorrow. The limit switches will have to wait till some more signs are complete. My wife is calling herself a Mechmate widow.

Well it is ready to cut. I have been jogging it around the table with the spinning spindle in the air. I have to sit down and study Mach a little more and cut something. I sold my dust collector and gave my spoilboard cutter and endmills to the man that bought my shopbot. So I am waiting for some bits to come in from Onsrud. Got to get something collecting dust before I surface my spoilboard. You only make that mistake once!
I don't know if I have thanked Gerald and everybody else that has helped but thank you very much! This machine is awesome, just jogging it around i can see how smooth and fast it operates, I love it!! |

The top speed in Mach, at least in the "motor tuning" dialog box is 490ipm. That is probably fast enough for all practical purposes but I was wondering how JR got 1150 out of his? I would imagine it would be because his belt reduction is only 4 to 1 where my gear is 7.2 to 1. Is this a correct theory?
|
#88
|
|||
|
|||
If I remember correctly, JR started out using his motors direct drive, which meant that he had double-stack motors (double set of magnets on the longer armature, motor length about 90 to 100mm). The 7.2:1 reduction motors are single-stack.

Gerald that is correct. My motors are PK299-01AA, however they need way more voltage than my Geckos can handle. I'm thinking my next one will have PK299-F4.5 or the equivalent in a Chinese motor. Don't get me wrong ..... I'm not complaining.

Here you go!!! The first cut!! Cutting a part for a temporary dust foot.
