Marnus manages fibre laser sheet cutting and nesting
Marnus is responsible for making sure every CutLine installation in Gauteng runs smoothly. He focuses on the details that matter: pierce sequence, part orientation, and minimising waste. Whether it's a one-off urgent job or a full production run, Marnus works hands-on with job shops to review their workflow and get the most out of their system.
He handles day-to-day technical questions, site visits for new setups at customer sites, and first-article reviews at Sunnyrock HQ. When a client needs help with a tricky material or a nest that's not quite giving the best yield, Marnus steps in to fine-tune the process.
Supporting CutLine, SheetNest Pro and job shop clients
Marnus’s main focus is on the CutLine 1500 systems and SheetNest Pro software, which are widely used for mild steel, stainless, galvanised, and aluminium sheet work in fabrication shops. His advice is especially valuable for workshops dealing with short-run production, interruptions in material supply, or changing part requirements.
He works directly with fabricators, signage makers, and maintenance teams who need reliable nest briefs and guidance on sheet utilisation. When clients bring in new types of steel, or face issues with thin gauge or coated material, Marnus helps adjust settings and review nesting strategies to avoid rework.

Marnus works with both new and returning clients, offering practical answers on machine use, best practices for specific materials, and how to get more out of every CutLine run. He makes sure clients are comfortable with both the hardware and the nesting software, and is always ready to help troubleshoot or improve a process.
