Latex paints will work fine. That includes water based primers too. What really needs to happen to the MDF is it needs to be sealed first. You can use Kilz as suggested above. Latex primers, oil...
You can probably get the components you have working with some tweaking.
I don't understand, either the switches are on (continuity) or they are off (no continuity). Or they are broken or have...
Is it possible that you have some funky switches?
The way to check would be a continuity tester or ohm meter that will read a partial connection. They should be either fully on or fully off. No...
I'm so confused. :)
Not really, it just takes a lot of mental sorting out of the different parts of the problem. Since I'm not a electronics engineer I haven't been through it a bunch of times and...
Alright, after thinking about this a little more and looking at the pictures of your BOB, here's my guess.
The end of your limit switches should be connected to the signal ground since that...
The parallel port coming from your computer has several lines that are grounded. This is assuming you are using the proper power cables to your computer. And also that your power system that you are...
Which Break Out Board are you using?
This is just a stab at the problem but it sounds like you have a floating ground. Where it's not 0 volts and is floating too close to the trip point.
Here is a...
Ground loops?
Your shielding should be connected to ground in only one place. If your grounded shielding touches ground again you have just created a ground loop.

How about CamBam? Not a drawing program but will edit .dxf files and process them to gcode.
It's still in beta but getting better all the time. Free for the basic version. Or you can buy a full...
Let's not forget about the fact that you don't need a super computer to run EMC2. I'm using it on a 650 mhz PIII. Well maybe a little faster would be better for the GUI. But Ubuntu Linux and EMC get...
How about a different regulator?
Here's one that fairly common and available:
The LM317T is an adjustable regulator. It has a 40v voltage differential. That would just squeak in for 12 v. Or...
Thanks for the circuit Mariss.
It caused me to scratch my head for a second until I realized that you also have to have a switch or button to your direction pin for forward or reverse.
:idea:...
A higher voltage supply will get the motors to spin faster.
Changing the resistors won't work. Sorry I had misread what size resistors you had so all I did was to verify that they were right for the...
Hi Dan,
The resistors are going to control the amperage going to your motors and not the voltage.
By my figuring 2 - 5Ω, 15 watt resistors, one for each phase of your motor, would deliver 1.44...
Thanks to all for the help.
I think that I have solved my problem!
I have done some rerouting and reorganizing of my 120v wiring.
It turns out that I had a couple of ground loops.
I have two...
I use an engraver. It's quick and dirty.
But, here's a link just for fun:
Electric Stencil
It's a cool site with lots of old projects: (check the Vintage Farm Plans Link)...
Al,
It an analog signal of ch 1 but it's inverted. My IPod looks cool on the scope. :)
I found another section in the manual where it say a bit more:
"CH 1 Out Jack. - Output terminal where...
Thanks for the compliment. Check this out though.
I just uploaded a picture of my new antenna. Just increased the area by about 120 sq in. :) Maybe that's why I'm having problems. :eek:
My new Y...
I am assuming that it is just an analog signal of what channel 1 is seeing. The quote above is just what the manual says. It doesn't give any other explanation.
I have seen these sound card O-scopes...
I have a BK Precision 2120 scope. It's a good scope but it's basic. No storage, 20 mhz, dual trace.
It has a Channel 1 output - "A 50Ω output is available for driving a frequency counter or other...
I'm using a "Todd" 600 watt, 24v switching supply that I picked up as surplus. Also I have a little power block that I am using as a 5v supply.
I know I checked it on my scope when I first bought...
Thank you, Master.

There already is a 470pf cap on the step line to the 7486. Is it possible that it isn't the right value?
Chris
Would the HC series chips still use 5v, and be pin for pin compatible with the TTL chips that are there?
Unfortunately, the chips aren't socketed so it would mean unsoldering the existing chips. :( ...
Phil,
The chips are plain 7400 series TTL. The logic is 7474 and 7486 to TIP 120 output transistors. There is also a diode on each output, I assume to limit the back EMF. Current limiting is thru...
Thanks everyone for your input I may not have licked the problem yet but your thoughts have led me closer to figuring it out.

It's not really obvious...
Dan- I will look into some other code as I would like to learn. Yes, string formatting, manipulation and file IO are things that would be important with the Hershey fonts. They are written in a...
Tom,
Thank you, that's a really good thought. My controller is very basic. It's a Kleinbauer "Piker". I think that it was designed to be very inexpensive. It works and does what it is supposed...
