<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">In KAUST, we did the replacement and alignment of the laser source for the DWL2000 tool, during the COVID pandemic (2020), with Heidelberg's assistance on WhatsApp. At that time it was almost
mandatory to do it this way as they couldn’t come to Saudi. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">The fact is that Heidelberg is expensive, they charged us the same price per hour as if it was a real service, in person. In my opinion, this is not fare, as we used more time, I'm not a laser
engineer, we were using Whatsapp, not even a video call, and it took me more time to adjust things. Based on my experience the customer service Heidelberg provide is far away from a good one. I feel they are not open to sharing maintenance procedures and sometimes
the suggestions they give when we ask for solving a problem are very poor, like "Have you tried restarting the tool?".

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">Depending on the service engineer assigned to your tool you will get better or worse assistance.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">We also have an MLA150 and last year the laser power got very low and It had to be replaced. Yes they are expensive, I´d already bought one to have onsite as a spare and reduce downtime. When the time came
HIMT would not send me a procedure or offer to do some of the job remotely we had to have a service visit. I guess there are some differences between the DWL and the MLA. The engineer did have to do a fair amount of work in the software. The difference
may just be HIMT´s own experience with the replacement.<o:p></o:p></span></p>

no service visit. You would need to talk to them about that. Purchasing from Renishaw directly was only about 2K less when they quoted me and there is no installation guarantee. <o:p></o:p></span></p>

the signal is getting weaker. Heidelberg quoted us the cost for a refurbished laser unit, and we were surprised by how expensive it was. I was wondering how owners of other Heidelberg Instruments tools have proceeded in this situation? Does everyone just get
the unit directly from Heidelberg, or has anyone attempted any thriftier alternatives such as repairing or replacing themselves?<o:p></o:p></span></p>
