Construction of a steel plasma cutting machine

I built a guide with a drive for plasma cutting steel. I used 25mm guides for the construction, so I'm 100% sure the cutting line will be straight. I used a 24VDC motor, which powers the entire carriage via a gear. The gear rack is 20mm wide. An additional advantage is the laser that shows the cutting lines and the magnets that make the machine portable. The plasma cutter is a SKANDI KRAFT iTECH CUT 45 PFC.
