Hi i just bought everything for my new cnc machine but i only just realised that the drivers i bought for my stepper motors have a limit of 1.5 amps, and my steppers require 3.5amps
here are the parts in question

I plan on building a cnc with a 1mx0.5mx0.3m milling space, linear rails, screwball rods etc. as this is large i panicked and bought large steppers (for fear of not being able to move my plywood gantry) and without checking if my driver can power them, I'm hoping against hope that maybe i'm worrying about nothing, I've invested quit a bit with equipment surrounding my DV8825 drivers so if i need to change anything it will be the steppers,
the description of my DV8825 drivers says "It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow"
does this mean that each motor can have 3 amps as there is 2 phases per motor? and that if i have a heat sink and fan (which i do) then can I up the amps even further, to the required 3.5?
if there is indeed a problem here can you guys recommend the cheapest way out as i'm broke after buying all this equipment.

thanks in advance i don't know who else to ask!

The answer is yes but it's Not good choice for long time running.
