If vectors are going fast when they should be slow, or antibacklash vectors have disappeared,
look for a VM command.
Again, it is a good idea to send the IN command at the beginning of each move sequence.
The Carriage Crashes Into The Sides
Make sure your program does a Find Home operation at the start, or do a manual
re-reference by pressing FAST with GO TO ORIGIN.
Make sure the travel limits have been set correctly for the size of your platen and the
resolution; use the OL and TL commands. Check the applicable personality parameters with
OP.
Make sure the resolution is what it should be, with the RE command. Check the applicable
personality parameters with OP.
Be sure you are not sending an SP command which confuses the System about where the
carriage is with respect to the platen.
The Move Pattern Is the Wrong Size or In the Wrong Place
Check the origin location with the OO command or by pressing the GO TO ORIGIN button.
Make sure the Origin hasn't been set to the wrong place by the BP command.
Check the calibration factors via the OF command. Check the applicable personality
parameters with OP.
Make sure the resolution is what it should be, with the RE command. Check the applicable
personality parameters with OP.
Be sure you are not sending an SP command which confuses the System about where the
carriage is with respect to the platen.
Make sure your program does a Find Home operation at the start, or do a manual
re-reference by pressing FAST with GO TO ORIGIN.
Be sure your program is sending the right values; try printing the numbers on the screen.
Look for syntax errors described in One Particular Command, above.
It Works OK For A While, Then Goes Crazy
You may be getting a buffer overflow, due to an improper input handshake. Be sure you are
using a handshake, either Hardwired DTR, Xon/Xoff, Enq/Ack, or Software Checking. See
Chapter 5.
To check for buffer overflow, use the
ESC.E command; see Chapter 6.
