I’m using v7 firmware and can not seem to move / cut using G1 command form a console with out the error:
<code>#### TRAP #### Attempted move G1Y1 with feed rate = zero</code>
Below is a dump of the settings for Y axis followed by a simple G1 Y1 command and the error it returns.
Is there something I have not set ? as clearly in the dump it says feed rate is set to 1000.
<code>
tinyg GCODE[mm] ok> $y
Y axis – Axismode 1 [0-10] $YMO1
Y axis – Seek rate 1500 mm/min $YSR1500
Y axis – Feed rate 1000 mm/min $YFR1000
Y axis – Travel/rev 10.00 mm $YTR10.00
Y axis – Travel hard limit 300 mm $YTH300
Y axis – Travel soft limit 285 mm $YTS285
Y axis – Step angle 1.80 degrees $YSA1.80
Y axis – Microsteps 8 [1,2,4,8] $YMI8
Y axis – Motor polarity 0 [0,1] $YPO0
Y axis – Power mgmt mode 1 [0,1] $YPW1
Y axis – Limit switch mode 1 [0,1] $YLI1
Y axis – Homing enabled 1 [0,1] $YHE1
Y axis – Homing seek rate 1350 mm/min $YHR1350
Y axis – Homing close rate 10 mm/min $YHC10
Y axis – Homing offset -150 mm $YHO-150
Y axis – Homing backoff 5 mm $YHB5
Your Y axis settings translate to:
Y axis mode: STANDARD
Y max seek: 500 steps/sec
Y max feed: 333 steps/sec
tinyg GCODE[mm] ok> g1 y1
#### TRAP #### Attempted move G1Y1 with feed rate = zero</code>
what am i missing ?
G0 / Traverse commands work .
September 26, 2012 at 11:25 am #3526aldenMemberWhen you enter a G1 (or G2 or G3) command it requires an F word (not THAT F word). Examples:
G1 F400 x10 (or)
G1 X10 F400
G0’s do not. The feed rate in the settings is the maximum feed rate that the axis / motors can handle. If you specify an F word faster than the max it will be limited to the max you have set.
Does this help?

I also see that you only need to set the Feed Rate this way i.e within a G1 command, once.Then you can execute G1 commands omitting the feed rate.
I simply presumed that setting the Motor Feed Rate using $xfr1000 for example, set the feed rate there and then, like as if it was contained in a G1 command.
But I see that it is in fact a maximum value parameter, not simply setting the feed rate for the step.
thanks.
