To have full shutdown with logic control could I make these changes?  <BR>
Replace RN5 with 1100R and RN5C with 680E.<BR>
Then when pin1 is high ref voltage would be 0.29v (full power)<BR>
and when high ref would be 3v (shut down)<BR>
Am I missing something?</BLOCKQUOTE>

There are some barcodes that can be encoded as PCL fonts which basically map the data to a barcode image, but QR is not one of them. Code 128 is, but you still need a program to calculate the checksum and encode the data.' at: '<!-- 42018.0527199074 EOR -->'

I want to print bar code, can I use HP pcl print qr code and code 128?

<A HREF="http://www.cnczone.com/forums/stepper-motors-drives/251080-cnc-forum-post1631846.html#post1631846">jtrantow says</A> (speaking about his experience with a cheap THB6064AH knock off from China that would only turn one direction if at all) "Notice massmind design uses a 10k pullup in conjunction with the TB6564AH internal pulldown so it won't have this problem. This is an easy fix if you don't mind working with the three surface mount resistors, but I wish I had been aware of the massmind kit. <b>It would have been quicker to build up the kit than debug and repair this board.</b>"

The explanation I found easiest to understand is that of the "additive inverse" or the number you add to something to make it "go away" or rather, to make all but the highest digit zero. This is effectively the negative of the number if you drop the top digit.
<P>
So, the inverse of 25 is 75, because 25+75=100 and you drop the 1. So to subtract 25 from, say, 50, you add 75 instead and get 125, drop the 1, 25 is 50-25. 
<P>
Another example: The inverse of 2 is 8 because 2 and 8 are 10 (drop the 1). So to subtract 2 from 7 for example, just add 7 and 8 which is 15, drop the 1, answer is 5. 
<P>
When we work with a fixed number of digits, dropping the 1 (the overflow) is easy... and only requires a small adjustment to the way we find the inverse. Let's say we will stick to 4 digits always. That makes the inverse of 25 (actually 0025) become 9975. And the inverse of 0002 is 9998. Everything still works, 0050+9975=(1)0025, and 0007+9998=(1)0005. 
<P>
We just have to remember that the normal human convention of not writing leading zeros and always expanding to the left as far as we need, isn't use.
